| ○ | ○ | Article | Alkaline Treatment Variables to Characterize Poly(Vinyl Alcohol)/Poly(Vinyl Butyral/Vinyl Alcohol) Blend Films | Novel poly(vinyl alcohol) (PVA)/poly(vinyl butyral-vinyl alcohol) (P(VB-VA)) films with improved hydrophobicity were prepared from poly(vinyl acetate) (PVAc)/poly(vinyl butyral) (PVB) blend films with various mass ratios by saponification in a heterogeneous medium. The successful conversion of PVAc to PVA and PVAc/PVB to PVA/P(VB-VA) films was confirmed by Fourier transform infrared spectrometry, X-ray diffraction, and proton nuclear magnetic resonance analysis. This study also shows that the degree of saponification (DS) depends on the saponification time. The maximum DS of 99.99% was obtained at 96 h of saponification for all films, and the presence of PVB did not affect the DS at saponification times of 48-96 h. The effects of the PVAc/PVB blend ratio before and after saponification were determined by contact angle measurement, and the hydrophobicity was found to increase in both cases with increasing PVB content. Additionally, all the films exhibited improved mechanical properties after saponification, and the treated films possessed an unusual porous and uneven surface, in contrast with the untreated films. The prepared films with improved hydrophobicity can be used for various applications, such as biomaterials, filters, and medical devices. | Yang, Seong Baek; Karim, Mohammad Rezaul; Lee, Jungeon; Yeum, Jeong Hyun; Yeasmin, Sabina | Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; King Saud Univ, Ctr Excellence Res Engn Mat, Deanship Sci Res, Riyadh 11421, Saudi Arabia; King Saud Univ, Energy Res & Innovat Ctr, King Abdullah City Atom & Renewable Energy KA CAR, Riyadh 11451, Saudi Arabia | ; Yang, Seong/AAP-1745-2020; Karim, Mohammad Rezaul/D-7307-2012; Karim, Mohammad/NMK-8432-2025 | 56258526300; 56820318000; 57559595700; 6602257098; 57216565706 | jhyeum@knu.ac.kr;yeasminsabina44@yahoo.com; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 18 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.67 | 2025-06-25 | 8 | 9 | poly(vinyl alcohol); poly(vinyl butyral); heterogeneous saponification; blend film | HETEROGENEOUS SAPONIFICATION; SUSPENSION POLYMERIZATION; MICROSPHERES; NANOFIBERS; ACETATE; PVA | blend film; heterogeneous saponification; poly(vinyl alcohol); poly(vinyl butyral) | Contact angle; Film preparation; Hydrolysis; Hydrophobicity; Polyvinyl alcohols; Blend films; Heterogeneous saponification; Poly (vinyl alcohol) (PVA); Poly(vinyl acetate); Poly(vinyl alcohol); Poly(vinyl alcohol) (PVA); Poly(vinyl butyral); Vinylalcohol; Fourier transform infrared spectroscopy | English | 2022 | 2022-09 | 10.3390/polym14183916 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Aluminum Diethylphosphinate-Incorporated Flame-Retardant Polyacrylonitrile Separators for Safety of Lithium-Ion Batteries | Herein, we developed polyacrylonitrile (PAN)-based nanoporous composite membranes incorporating aluminum diethylphosphinate (ADEP) for use as a heat-resistant and flame-retardant separator in high-performance and safe lithium-ion batteries (LIBs). ADEP is phosphorus-rich, thermally stable, and flame retardant, and it can effectively suppress the combustibility of PAN nanofibers. Nanofibrous membranes were obtained by electrospinning, and the content of ADEP varied from 0 to 20 wt%. From the vertical burning test, it was demonstrated that the flame retardancy of the composite membranes was enhanced when more than 5 wt% of ADEP was added to PAN, potentially increasing the safety level of LIBs. Moreover, the composite membrane showed higher ionic conductivity and electrolyte uptake (0.83 mS/cm and 137%) compared to those of commercial polypropylene (PP) membranes (Celgard 2400: 0.65 mS/cm and 63%), resulting from interconnected pores and the polar chemical composition in the composite membranes. In terms of battery performance, the composite membrane showed highly stable electrochemical and heat-resistant properties, including superior discharge capacity when compared to Celgard 2400, indicating that the PAN/ADEP composite membrane has the potential to be used as a heat-resistant and flame-retardant separator for safe and high-power LIBs. | Kang, Seok Hyeon; Jeong, Hwan Yeop; Kim, Tae Ho; Lee, Jang Yong; Hong, Sung Kwon; Hong, Young Taik; Choi, Jaewon; So, Soonyong; Yoon, Sang Jun; Yu, Duk Man | Korea Res Inst Chem Technol KRICT, Energy Mat Res Ctr, Daejeon 34114, South Korea; Chungnam Natl Univ, Dept Polymer Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea | So, Soonyong/AAO-5321-2020; Hong, Young/AAO-4513-2020; LEE, JI SOOK/HOF-9112-2023 | 57441948300; 57193333422; 57189330960; 56083638300; 8070084200; 7403391571; 57210206972; 35077284800; 56564523300; 49865015000 | mlc1207@krict.re.kr;hwanyeop@krict.re.kr;thkim@krict.re.kr;ljylee@krict.re.kr;skhong@cnu.ac.kr;ythong@krict.re.kr;jwchoi@knu.ac.kr;syso@krict.re.kr;sjyoon@krict.re.kr;dmyu@krict.re.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 9 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.45 | 2025-06-25 | 4 | 6 | polyacrylonitrile separator; phosphinate; heat resistance; flame retardant; lithium-ion battery | THERMALLY-STABLE SEPARATOR; NONWOVEN SEPARATOR; COMPOSITE SEPARATOR; ISSUES; MEMBRANES; MECHANISMS; CHALLENGES | flame retardant; heat resistance; lithium-ion battery; phosphinate; polyacrylonitrile separator | Aluminum; Electrolytes; Heat resistance; Ions; Lithium-ion batteries; Nanofibers; Polypropylenes; Separators; Heat resistance; Heat resistant; Nanofibrous membranes; Nanoporous composite; Performance; Phosphinate; Polyacrylonitrile nanofibre; Polyacrylonitrile separator; Thermally stable; Vertical burning tests; Composite membranes | English | 2022 | 2022-05 | 10.3390/polym14091649 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Anion Exchange Membranes for Fuel Cell Application: A Review | The fuel cell industry is the most promising industry in terms of the advancement of clean and safe technologies for sustainable energy generation. The polymer electrolyte membrane fuel cell is divided into two parts: anion exchange membrane fuel cells (AEMFCs) and proton exchange membrane fuel cells (PEMFCs). In the case of PEMFCs, high-power density was secured and research and development for commercialization have made significant progress. However, there are technical limitations and high-cost issues for the use of precious metal catalysts including Pt, the durability of catalysts, bipolar plates, and membranes, and the use of hydrogen to ensure system stability. On the contrary, AEMFCs have been used as low-platinum or non-platinum catalysts and have a low activation energy of oxygen reduction reaction, so many studies have been conducted to find alternatives to overcome the problems of PEMFCs in the last decade. At the core of ensuring the power density of AEMFCs is the anion exchange membrane (AEM) which is less durable and less conductive than the cation exchange membrane. AEMFCs are a promising technology that can solve the high-cost problem of PEMFCs that have reached technological saturation and overcome technical limitations. This review focuses on the various aspects of AEMs for AEMFCs application. | Das, Gautam; Choi, Ji-Hyeok; Nguyen, Phan Khanh Thinh; Kim, Dong-Joo; Yoon, Young Soo | Kyungpook Natl Univ, Sch Appl Chem Engn, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Gachon Univ, Dept Mat Sci & Engn, Seongnam 13120, Gyeonggi Do, South Korea; Gachon Univ, Dept Chem & Biol Engn, Seongnam 13120, South Korea; Auburn Univ, Mat Res & Educ Ctr, 275 Wilmore Labs, Auburn, AL 36849 USA | KIM, DONG-JOO/C-2277-2008; Kim, Dong-Joo/C-2277-2008; NGUYEN, PHAN/KZV-0772-2024; Yoon, Young Soo/LYO-5503-2024 | 24358918500; 57546373500; 57217825189; 12798929800; 55647164856 | gautam2706@gmail.com;joshua9456@gachon.ac.kr;thinhnpk@gachon.ac.kr;dkim@auburn.edu;benedicto@gachon.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 6 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 2.76 | 2025-06-25 | 114 | 116 | alkali stability; ionic conductivity; power density; non-platinum catalyst; low cost; anion exchange membrane; fuel cell; renewable energy | POLYMER ELECTROLYTE MEMBRANES; RADIATION-GRAFTED MEMBRANES; POLY(ARYLENE ETHER SULFONE); HYDROXIDE ION CONDUCTIVITY; WATER MANAGEMENT; POLY(PHENYLENE OXIDE); POLY(VINYL ALCOHOL); PROTON TRANSPORT; HYBRID MEMBRANES; CARBON-DIOXIDE | alkali stability; anion exchange membrane; fuel cell; ionic conductivity; low cost; non-platinum catalyst; power density; renewable energy | Activation energy; Alkaline fuel cells; Catalysts; Costs; Electrolytic reduction; Gas fuel purification; Ion exchange; Ion exchange membranes; Ions; Platinum; Polyelectrolytes; System stability; Alkali stability; Anion-exchange membrane fuel cells; Cell/B.E; Low-costs; Non-platinum; Non-platinum catalyst; Platinum catalysts; Power densities; Proton-exchange membranes fuel cells; Renewable energies; Proton exchange membrane fuel cells (PEMFC) | English | 2022 | 2022-03 | 10.3390/polym14061197 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bioabsorbable Carboxymethyl Starch-Calcium Ionic Assembly Powder as a Hemostatic Agent | In contrast to hemostatic fabrics, foams, and gels, hemostatic spray powders may be conveniently applied on narrow and complex bleeding sites. However, powdered hemostatic agents are easily desorbed from the bleeding surface because of blood flow, which seriously decreases their hemostatic function. In this study, the hemostatic performance of a bioabsorbable powder with decreased desorption was investigated. The proposed hemostatic powder (OOZFIX (TM)) is an ionic assembly of carboxymethyl starch and calcium. The microstructure and chemical properties of the hemostatic powder were analyzed. The hemostatic performance (blood absorption, blood absorption rate, and coagulation time), thromboelastography (TEG), rheology, adhesion force, and C3a complement activation of the OOZFIX (TM) were evaluated and compared with those of the carboxymethyl starch-based commercial hemostatic powder (Arista (TM) AH). The in vivo rat hepatic hemorrhage model for hemostasis time and bioabsorption of the OOZFIX (TM) showed quick biodegradation (<3 weeks) and a significantly improved hemostasis rate (78 +/- 17 s) compared to that of Arista AH (182 +/- 11) because of the reduced desorption. The bioabsorbable hemostatic powder OOZFIX (TM) is expected to be a promising hemostatic agent for precise medical surgical treatments. | Ko, Young-Gwang; Kim, Byeong Nam; Kim, Eun Jin; Chung, Ho Yun; Park, Seong Yong; Kim, Young-Jin; Kwon, Oh Hyeong | Kumoh Natl Inst Technol, Dept Polymer Sci & Engn, Gumi 39177, South Korea; Theracion Biomed Co Ltd, Seongnam 13201, South Korea; Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, CMRI, Daegu 41944, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Sch Med, Dept Thorac & Cardiovasc Surg, Seoul 06351, South Korea; Daegu Catholic Univ, Dept Adv Mat & Chem Engn, Gyongsan 38430, South Korea | ; Park, Seong Yong/IZQ-1385-2023 | 35812149900; 57214661586; 55705551300; 7404007181; 48661337600; 56195058400; 55665582200 | ohkwon@kumoh.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 18 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 1.2 | 2025-06-25 | 16 | 16 | powder; carboxymethyl starch; calcium; hemostatic agent | LIVER SURGERY; RISK-FACTORS; HEMORRHAGE | calcium; carboxymethyl starch; hemostatic agent; powder | Biodegradation; Blood; Chemical analysis; Desorption; Starch; Absorption rates; Bioabsorbable; Bleedings; Blood flow; Carboxymethyl starch; Haemostasis; Hemostatic agents; Ionic assemblies; Performance; Spray powders; Calcium | English | 2022 | 2022-09 | 10.3390/polym14183909 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Design of Eco-Friendly Self-Healing Polymers Containing Hindered Urea-Based Dynamic Reversible Bonds | This work describes an emulsion polymer with self-healing capability based on a dynamic covalent bonding mechanism. A latex prepolymer (LPtB) containing bulky amine units was synthesized via soap-free emulsion polymerization. Then, a one-pot crosslinkable self-healing emulsion polymer was prepared by adding a blocked isocyanurate and a catalyst into the latex prepolymer, and subsequently, a crosslinked self-healing polymer film (cLPtB) was prepared. Syntheses of self-healing polymers were confirmed by Fourier transform infrared, size exclusion chromatography, proton nuclear magnetic resonance, dynamic light scattering, and transmission electron microscopy analyses. A control latex prepolymer (LPH) was also synthesized without bulky amine functionality, and the self-healing properties of crosslinked LPH (cLPH) were compared to those of cLPtB under the same crosslinking and healing conditions. In addition, the effects of drying and crosslinking conditions at various temperatures on the film formation and crosslinking degree of polymer films were evaluated through atomic force microscopy and gel content analysis. cLPtB demonstrated a TgDMAof 47 °C and onset dissociation of urea linkages at 120 °C, as confirmed by DMA. The cLPtB films exhibited complete restoration of mechanical properties after cutting and healing at a film formation temperature of 80 °C; they exhibited a self-healing efficiency (σSHE%) of 100%. The cLPtB coating surface also manifested a rapid healing process with 100% wound suturing at 100 °C for 5 min, as recorded by optical microscopy. © 2022 by the Author(s). | Ahmed, Sana; Bae, Mi Ju; Jeong, Subin; Lee, Ju Hyun; Kim, Jin Chul; Park, Young Il; Cheong, In Woo | Department of Applied Chemistry, Engineering School, Kyungpook National University, Daegu, 41566, South Korea; Research Center for Green Fine Chemicals, Korea Research Institute of Chemical Technology, Ulsan, 44412, South Korea; Research Center for Green Fine Chemicals, Korea Research Institute of Chemical Technology, Ulsan, 44412, South Korea; Research Center for Green Fine Chemicals, Korea Research Institute of Chemical Technology, Ulsan, 44412, South Korea; Research Center for Green Fine Chemicals, Korea Research Institute of Chemical Technology, Ulsan, 44412, South Korea; Research Center for Green Fine Chemicals, Korea Research Institute of Chemical Technology, Ulsan, 44412, South Korea; Department of Applied Chemistry, Engineering School, Kyungpook National University, Daegu, 41566, South Korea | 57444624300; 57578177000; 57683018600; 57947597000; 56805502600; 55494480300; 7006733373 | jckim81@krict.re.kr;ypark@krict.re.kr;inwoo@knu.ac.kr; | ACS Applied Polymer Materials | ACS APPL POLYM MATER | 2637-6105 | 2637-6105 | 4 | 11 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.79 | 2025-06-25 | 9 | emulsion; film formation; hindered urea bond; latex; self-healing, water-borne | Crosslinking; Dynamics; Emulsification; Emulsion polymerization; Film preparation; High resolution transmission electron microscopy; Light scattering; Light transmission; Metabolism; Monomers; Polymer films; Self-healing materials; Size exclusion chromatography; Crosslinked; Emulsion polymers; Film formations; Hindered urea bond; Prepolymers; Self-healing; Self-healing polymers; Self-healing, water-borne; Synthesised; Water-borne; Urea | English | Final | 2022 | 10.1021/acsapm.2c01087 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Article | Development and Characterization of Biocomposite Films Based on Polysaccharides Derived from Okra Plant Waste for Food Packaging Application | Polysaccharide-based composite films were developed using mucilage polysaccharides (OLP) and carboxymethyl cellulose (CMC) extracted from okra leafstalk wastes. The rheological properties of biocomposite OLP/CMC film-forming solutions were characterized using the Power-law model, and fabricated films were characterized for their potential food packaging applications. OLP/CMC solutions exhibited pseudo-plastic fluid characteristics and differences in rheological behavior (n, 0.478-0.743), and flow consistency (K, 1.731-9.154) with increasing content of OLP (5 to 30 % w/w of CMC) were associated with variations in the physical, mechanical, and barrier properties of films. Surface hydrophobicity (24%) increased and oxygen (39%) and water vapor (32%) permeability reduced in OLP/CMC films containing up to 10% OLP. Moreover, a higher content of OLP enhanced the antioxidant activity and thermal stability of OLP/CMC films. Subsequently, OLP/CMC was applied as a coating to preserve cherry tomatoes for 14 days at 30 degrees C. Quality deterioration characterized by high weight loss (22%), firmness loss (74.62%), and discoloration ( increment E, 21.26) occurred in uncoated tomatoes and were within unusable/unmarketable limits based on their visual quality score. In contrast, OLP/CMC effectively minimized quality losses, and coated tomatoes exceeded the limit of marketability after 14 days of storage. This study successfully applied value-added polysaccharides derived from okra plant residues for edible food packaging. | Olawuyi, Ibukunoluwa Fola; Lee, Won Young | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Tailored Food Technol, Daegu 41566, South Korea | Olawuyi, Ibukunoluwa/H-1232-2018; Lee, Wonyoung/AAL-2780-2021 | 57204471854; 57195940408 | wonyoung@knu.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 22 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 2.09 | 2025-06-25 | 24 | 28 | biocomposite films; okra waste; biopolymer; packaging; tomatoes; preservation | CARBOXYMETHYL CELLULOSE; EDIBLE COATINGS; SHELF-LIFE; MUCILAGE; ANTIOXIDANT; QUALITY; PRESERVATION; VEGETABLES; CHITOSAN; BARRIER | biocomposite films; biopolymer; okra waste; packaging; preservation; tomatoes | Coatings; Degradation; Food Storage; Fruits; Polysaccharides; Rheology; Cellulose films; Coatings; Composite films; Deterioration; Food storage; Fruits; Polysaccharides; Rheology; Thermodynamic stability; Biocomposite; Biocomposite films; Carboxymethyl cellulose; Food packaging; Okra waste; Packaging applications; Plant wastes; Preservation; Rheological property; Tomato; Biopolymers | English | 2022 | 2022-11 | 10.3390/polym14224884 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development of an Atmospheric Pressure Plasma Jet Device Using Four-Bore Tubing and Its Applications of In-Liquid Material Decomposition and Solution Plasma Polymerization | In this study, we describe an atmospheric pressure plasma jet (APPJ) device made of four-bore tubing operable in inhospitable humid environments and introduce two potential applications of liquid material processing: decomposition of aqueous phosphorus compounds and solution-plasma polymerization. A four-bore tube was used as the plasma transfer conduit and two diagonal bores contained metal wires. In the proposed APPJ device, the metal wires serving as electrodes are completely enclosed inside the holes of the multi-bore glass tube. This feature allows the APPJ device to operate both safely and reliably in humid environments or even underwater. Thus, we demonstrate that the proposed electrode-embedded APPJ device can effectively decompose aqueous phosphorus compounds into their phosphate form by directly processing the solution sample. As another application of the proposed APPJ device, we also present the successful synthesis of polypyrrole nanoparticles by solution plasma polymerization in liquid pyrrole. | Bae, Gyu Tae; Jang, Hyo Jun; Jung, Eun Young; Lee, Ye Rin; Park, Choon-Sang; Kim, Jae Young; Tae, Heung-Sik | Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll IT Engn, Inst Elect Technol, Daegu 41566, South Korea; Milligan Univ, Dept Elect Engn, Johnson City, TN 37682 USA; Kyungpook Natl Univ, Coll IT Engn, Sch Elect Engn, Daegu 41566, South Korea | 57202369078; 57207956623; 57203199724; 57977013900; 16025295400; 57205191453; 7006298844 | jyk@knu.ac.kr;hstae@ee.knu.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 22 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.45 | 2025-06-25 | 6 | 6 | atmospheric pressure plasma; multi-bore tube; phosphorus compound decomposition; plasma polymerization; plasma processing; plasma treatment | TOTAL PHOSPHORUS; ORGANIC-COMPOUNDS; NATURAL-WATERS; DISCHARGE; TUBE | atmospheric pressure plasma; multi-bore tube; phosphorus compound decomposition; plasma polymerization; plasma processing; plasma treatment | Atmospheric pressure; Electrodes; Liquids; Phosphorus compounds; Plasma polymerization; Polypyrroles; Synthesis (chemical); Atmospheric pressure plasma jets; Atmospheric pressure plasmas; Compound decomposition; Humid environment; Liquid materials; Metal wires; Multi-bore tube; Phosphorus compound decomposition; Plasma treatment; Solution plasmas; Plasma applications | English | 2022 | 2022-11 | 10.3390/polym14224917 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of the Particle Size and Layer Thickness of GNP Fillers on the Dielectric Properties and Actuated Strain of GNP-PDMS Composites | Dielectric elastomer actuators (DEAs), a type of electroactive polymers (EAPs), are smart materials that are used in various fields such as artificial muscles and biomimetic robots. In this study, graphene nanoplatelets (GNPs), which are conductive carbon fillers, were added to a widely used DEA, namely, polydimethylsiloxane (PDMS), to improve its low actuated strain. Four grades of GNPs were used: H5, H25, M5, and M25 (here, the number following the letter indicates the average particle size of the GNPs in mu m). The average layer thickness of the H grade is 13-14 nm and that of the M grade is 5-7 nm. PDMS composites were prepared by adding 0.5, 1, 2, and 3 wt% of each GNP, following which the mechanical properties, dielectric properties, and actuated strain of the composites were measured. The mechanical properties were found to increase as the particle size increased. Regarding the dielectric characteristics, it was found that the higher the aspect ratio of the filler, the easier the formation of a micro-capacitor network in the composite-this led to an increase in the dielectric constant. In addition, the higher amounts of GNPs in the composites also led to an increase in the dielectric constant. For the actuated strain analysis, the electromechanical sensitivity was calculated using the ratio of the dielectric constant to the Young's modulus, which is proportional to the strain. However, it was found that when the loss tangent was high, the performance of the actuated strain decreased owing to the conversion of electric energy into thermal energy and leakage current loss. As a result, the highest actuated strain was exhibited by the M25 composite, with an actuated strain value of 3.01% measured at a low electric field (<4 kV/mm). In conclusion, we proved that the GNP-PDMS composites with a thin layer and large particle size exhibited high deformation. | Seo, Jin-Sung; Kim, Do-Hyeon; Jung, Heon-Seob; Kim, Ho-Dong; Choi, Jaewon; Kim, Minjae; Baeck, Sung-Hyeon; Shim, Sang-Eun | Inha Univ, Educ & Res Ctr Smart Energy & Mat, Dept Chem & Chem Engn, Incheon 22212, South Korea; 150 Hyundai Res Ctr, Gyeonggi Do 18280, Hwaseong Si, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Handong Global Univ, Sch Mech & Control Engn, 558 Handong Ro, Pohang 37554, Gyeongbuk, South Korea | 59177774900; 57907776600; 57198760937; 57906991000; 57210206972; 59445868800; 6601966563; 7202796134 | seshim@inha.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 18 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.22 | 2025-06-25 | 3 | 3 | electro active polymers; dielectric elastomer actuator; polydimethylsiloxane; graphene nanoplatelets; dielectric constant; loss tangent; actuated strain; composite | ELECTROACTIVE POLYMERS; MAXWELL STRESS; ELASTOMER; ELECTRODES | actuated strain; composite; dielectric constant; dielectric elastomer actuator; electro active polymers; graphene nanoplatelets; loss tangent; polydimethylsiloxane | Aspect ratio; Biomimetics; Conducting polymers; Dielectric materials; Elastomers; Electric fields; Electric losses; Electroactive polymer actuators; Fillers; Graphene; Microchannels; Particle size; Particle size analysis; Permittivity; Silicones; Strain; Actuated strain; Artificial muscle; Dielectric elastomer actuators; Dielectrics property; Electroactive polymers; Graphene nanoplatelets; Layer thickness; Loss tangent; Particle layer; Particles sizes; Polydimethylsiloxane | English | 2022 | 2022-09 | 10.3390/polym14183824 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Electrospun Poly(Styrene-Co-Vinylbenzyl Chloride-Co-Acrylonitrile) Nanofiber Mat as an Anion Exchange Membrane for Fuel Cell Applications | A nanofiber mat of styrene-co-vinylbenzyl chloride-co-acrylonitrile copolymer as an anion exchange membrane (AEM) was synthesized via the electrospinning of organic reaction mixtures. The synthesized membranes were characterized using FT-IR spectroscopy for structural analysis. The AEM demonstrated a high ionic conductivity mainly due to the phase segregation in the membrane structure, as analyzed by transmission electron microscopy (TEM). The membrane properties such as water uptake, swelling ratio, and ion exchange capacity, as well as ionic conductivity, varied with the chemical composition. With the molar ratio of styrene, vinylbenzyl chloride, and acrylonitrile at 3:5:2, the highest ionic conductivity of 0.214 S cm(-1) at 80 degrees C was observed. Additionally, the AEM retained 94% of original conductivity after 72 h of soaking in 1 M KOH solution. | Kang, Dongho; Lee, Ji Su; Yoon, Hyon Hee; Sharma, Chinta Mani; Das, Gautam; Yoon, Young Soo | Gachon Univ, Dept Chem & Biol Engn, Seongnam 461701, South Korea; Biswanath Coll, Dept Chem, Biwanath Charialli 784176, India; Kyungpook Natl Univ, Sch Appl Sci, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Gachon Univ, Dept Mat Sci & Engn, Seongnam 461701, South Korea | ; Sharma, Chandra/GXZ-7383-2022; Yoon, Young Soo/LYO-5503-2024; Yoon, Hyon/AAW-7807-2020 | 57208181795; 57879820600; 55663131500; 54915023300; 24358918500; 55647164856 | gautam2706@gmail.com;benedicto@gachon.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 16 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.45 | 2025-06-25 | 5 | 6 | anion exchange membrane; styrene-co-vinylbenzyl; chloride-co-acrylonitrile; electrospinning; nanofiber mat; ion conductivity | PERFORMANCE | anion exchange membrane; chloride-co-acrylonitrile; electrospinning; ion conductivity; nanofiber mat; styrene-co-vinylbenzyl | Alkaline fuel cells; Electrospinning; High resolution transmission electron microscopy; Ion exchange; Ion exchange membranes; Ionic conductivity; Ions; Molar ratio; Nanofibers; Potassium hydroxide; Anion exchange; Anion exchange membrane; Chloride-co-acrylonitrile; Electrospuns; Exchange membranes; Ion conductivities; Nanofiber mats; Styrene-co-vinylbenzyl; Synthesised; Vinyl-benzyl chlorides; Styrene | English | 2022 | 2022-08 | 10.3390/polym14163236 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Evaluation of Compressive Strength and Thermal Conductivity of Sand Stabilized with Epoxy Emulsion and Polymer Solution | This paper presents findings obtained by evaluating the compressive strength, thermal conductivity, and durability of sand cylinder specimens stabilized with either epoxy emulsion (EM), acrylic polymer aqueous solution (APAS), EM-APAS mixture, or EM-APAS-lime mixture. Given the data obtained from the laboratory test, simulation analysis that uses a heat transfer fluid model of a ground-coupled heat pump (GCHP) system confirms the EM-APAS-lime binder performs best in the compressive strength and thermal conductivity; EM-APAS mixture performs best in the durability. However, the slake durability index of specimens containing EM-APAS-lime is equal to or greater than 80%. In addition, the compressive strength of sand stabilized with the EM-APAS-lime mixture is more than three times that of sand stabilized with cement. The thermal conductivity of sand stabilized with cement and that of sand treated with EM-APAS-lime mixture are 0.1 W/m center dot K and 0.9-1 W/m center dot K, respectively. It is confirmed that the heat collection of sand stabilized with EM-APAS-lime outperforms five times over that of sand stabilized with cement. These findings provide admissible evidence that the EM-APAS-lime mixture, which outperforms cement in compressive strength and thermal conductivity, is most suitable for ground improvement binder for GCHP systems. | Park, Sung-Sik; Park, Jun-Woo; Yoon, Keun-Byoung; Park, Il Seouk; Woo, Seung-Wook; Lee, Dong-Eun | Kyungpook Natl Univ, Dept Civil Engn, 80 Daehakro, Daegu 41566, South Korea; Daegu Urban Corp, 73 Chimsanro, Daegu 41594, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Mech Engn, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Architecture Civil Environm & Energy Engn, 80 Daehakro, Daegu 41566, South Korea | 36241850300; 57703809500; 7401607550; 50262800000; 57212917862; 56605563300 | sungpark@knu.ac.kr;jwpark@duco.or.kr;kbyoon@knu.ac.kr;einstein@knu.ac.kr;geowsw@knu.ac.kr;dolee@knu.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 10 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.37 | 2025-06-25 | 7 | 5 | sand stabilization; epoxy emulsion; acrylic polymer; ground-coupled heat pump; compressive strength; thermal conductivity; heat transfer fluid model | HEAT-PUMP; PERFORMANCE | acrylic polymer; compressive strength; epoxy emulsion; ground-coupled heat pump; heat transfer fluid model; sand stabilization; thermal conductivity | Cements; Compressive strength; Durability; Emulsification; Heat transfer; Lime; Mixtures; Thermal conductivity; Acrylic polymers; Epoxy; Epoxy emulsion; Fluid modeling; Ground coupled heat pump; Heat transfer fluid model; Heat transfer fluids; Polymer aqueous solution; Sand stabilization; Stabilized with cements; Sand | English | 2022 | 2022-05 | 10.3390/polym14101964 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Experimental and Digimat-FE Based Representative Volume Element Analysis of Dye-Mixed Colored Resin and Carbon Fiber | Recently, the automobile industry has demanded weight reduction, so research on materials is being actively conducted. Among this research, carbon fiber-reinforced composite materials are being studied a lot in the automobile industry due to their excellent mechanical properties, chemical resistance, and heat resistance. However, carbon fiber-reinforced composite materials have disadvantages, in that they are not free from color selection, and have weak interfacial bonding strength. In this study, a colored epoxy resin was prepared by mixing epoxy-which is a thermosetting resin according to the pigment concentration (0.1, 0.3, 0.5, 1.0 wt%)-and curing shrinkage. Thermal expansion characteristics were analyzed and the concentration of 0.5 wt% pigment showed the lowest shrinkage and thermal expansion characteristics. In addition, to measure the interfacial shear strength (IFSS) of the carbon fiber and the colored epoxy resin, the IFSS was obtained by performing a microdroplet debonding test, and the strength of the pigment concentration of 0.5 wt% was reduced to a relatively low level. Through these experiments, it was determined that an epoxy resin in which 0.5 wt% pigment is mixed is the optimal condition. Finally, using the composite material modeling software (Digimat 2020.0), the representative volume element (RVE) of the meso-scale was set, and interfacial properties of carbon fibers and colored epoxy resins were analyzed by interworking with general-purpose finite element analysis software (Abaqus CAE). | Sim, Jee-Hyun; Yeo, Dong-Hyeon; Yoon, Hyun-Sung; Yu, Seong-Hun; Lee, Do-Hyun; Bae, Jin-Seok | Kyungpook Natl Univ, Dept Textile Syst Engn, Daegu 41566, South Korea; Korea Dyeing & Finishing Technol Inst DYETEC Ins, Daegu 41706, South Korea | 57487015800; 57487015900; 57486848400; 57487349300; 57202299079; 8857273700 | maxwell02@dyetec.or.kr;jbae@knu.ac.kr; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 5 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.15 | 2025-06-25 | 2 | 2 | carbon fiber-reinforced plastic; resin transfer molding; interfacial adhesion; computer-aided engineering; representative volume element (RVE) model; epoxy resin | COMPOSITES | Carbon fiber-reinforced plastic; Computer-aided engineering; Epoxy resin; Interfacial adhesion; Representative volume element (RVE) model; Resin transfer molding | ABAQUS; Automotive industry; Chemical bonds; Epoxy resins; Fiber bonding; Fibers; Finite element method; Heat resistance; Resin transfer molding; Shrinkage; Thermal expansion; Volume measurement; Carbon fiber reinforced composite materials; Carbon-fibre reinforced plastics; Colored epoxy resin; Computer-aided engineering; Element models; Interfacial adhesions; Pigment concentration; Representative volume element model; Representative volume elements; Resin-transfer molding; Reinforcement | English | 2022 | 2022-03 | 10.3390/polym14051028 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Exploring inattentional blindness in failure of safety risk perception: Focusing on safety knowledge in construction industry | Inattentional blindness (IB) is a popular human error associated with selective attention or inattention. It can be depicted as an individual's failing to notice or recognize a visual object or event due to a lack of active attention in a given situation. Dynamic situations at construction sites often can lead to IB, which can cause failure of safety risk perception (FSRP) on hazards and lead to potential accidents. Few studies have focused on the importance of the IB concept in the construction industry. To overcome this gap, 53 supervisors participated in an experiment to analyze the performance of IB in FSRP and safety knowledge-related factors that affect IB and FSRP to establish practical safety management strategies. The results show that IB accounted for 50% of FSRP, validating the importance of IB. Other factors, such as certified training and frequent exposure to accidents, also had positive impacts on reducing IB. Certification and external training showed positive impacts in the low-experience group but not on the high-experience group. Based on these findings, the IB concept should be considered when addressing construction safety management. Practical safety management strategies to improve IB should be applied differently according to the supervisor's experience. | Park, SungJoon; Park, Chan Young; Lee, Changjun; Han, Seung Heon; Yun, Sungmin; Lee, Dong-Eun | HanmiGlobal Co Ltd, Seoul, South Korea; Kyungpook Natl Univ, Intelligent Construct Automat Ctr, Daegu, South Korea; Yonsei Univ, Dept Civil & Environm Engn, Seoul, South Korea; Yeungnam Univ, Dept Civil Engn, Gyongsan, South Korea; Kyungpook Natl Univ, Dept Architectural Engn, Daegu, South Korea | Yun, Sungmin/I-4320-2015; Park, Chan/F-5696-2010 | 57278478100; 57190000674; 57195408712; 23004849600; 26222001400; 56605563300 | smyun@yu.ac.kr;dolee@knu.ac.kr; | SAFETY SCIENCE | SAFETY SCI | 0925-7535 | 1879-1042 | 145 | SCIE | ENGINEERING, INDUSTRIAL;OPERATIONS RESEARCH & MANAGEMENT SCIENCE | 2022 | 6.1 | 18.0 | 3.83 | 2025-06-25 | 35 | 35 | Inattentional blindness; Hazard recognition; Construction safety risk perception; Safety knowledge; Safety management | HAZARD RECOGNITION; EYE-TRACKING; ATTENTION; IDENTIFICATION; SUPERVISORS; CAPTURE; IMPACT; SEE | Construction safety risk perception; Hazard recognition; Inattentional blindness; Safety knowledge; Safety management | Accident prevention; Accidents; Construction industry; Eye protection; Occupational risks; Risk perception; Supervisory personnel; Construction safety; Construction safety risk perception; Hazard recognition; Inattentional blindness; Management strategies; Safety knowledge; Safety management; Safety risks; Selective attention; Visual objects; adult; Article; building industry; certification; experience; female; hazard assessment; human; inattentional blindness; knowledge; male; occupational exposure; occupational safety; risk perception; training; visual attention; Hazards | English | 2022 | 2022-01 | 10.1016/j.ssci.2021.105518 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Fabrication of Novel Agrowaste (Banana and Potato Peels)-Based Biochar/TiO2 Nanocomposite for Adsorption of Cr(VI), Statistical Optimization via RSM Approach | In this research work, a simple, efficient, and eco-friendly procedure for the biosorption of Cr(VI) ions was studied. A detailed comparative study was performed to check the adsorption efficiency of agrowaste (banana and potato peels)-based adsorbents. Firstly, mixed biosorbent was washed, dried and ground into powder, secondly, biosorbent was pyrolyzed into biochar and thirdly TiO2 nanocomposite (TiO2 NC) biosorbent was made by sonicating using prepared biochar and TiO2 NPs. Titanium dioxide nanoparticles (TiO2 NPs) were synthesized by a green method using Psidium guajava leaf extract. The synthesized adsorbents were characterized by SEM, EDX FT-IR, XRD and UV-visible analysis. The effect of four different factors, i.e., pH of the synthetic metallic solution, time, concentration and adsorbent dosage was studied. The optimum conditions were time (120 min), pH (3), concentration (10 ppm) and adsorbent dosage (1.0 g). The kinetic modeling showed that the adsorption of Cr(VI) ion follows a pseudo second-order mechanism and the Langmuir isotherm model was found to fit better for this study. Response surface methodology (RSM)-based optimized parameters provided optimal parameter sets that better represent the adsorption rate models. The uptake capacity of Cr(VI) from aqueous solution was found to be biomass (76.49 mg/L) < biochar (86.51 mg/L) < TiO2 NC (92.89 mg/L). It can be suggested that the produced TiO2 NC could possibly be an efficient biosorbent for the removal of Cr(IV). | Ashfaq, Aamna; Nadeem, Raziya; Gong, Hongyu; Rashid, Umer; Noreen, Saima; Rehman, Shafique ur; Ahmed, Zubair; Adil, Muhammad; Akhtar, Nayab; Ashfaq, Muhammad Zeeshan; Alharthi, Fahad A.; Kazerooni, Elham Ahmed | Shandong Univ, Sch Mat Sci & Engn, Minist Educ, Key Lab Liquid Solid Struct Evolut & Proc Mat, Jinan 250061, Peoples R China; Univ Agr Faisalabad, Dept Chem, Faisalabad 38040, Pakistan; Univ Putra Malaysia, Inst Nanosci & Nanotechnol ION2, Serdang 43400, Selangor, Malaysia; Lahore Coll Women Univ, Dept Zool, Lahore 54000, Pakistan; King Saud Univ, Coll Sci, Chem Dept, Riyadh 1145, Saudi Arabia; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea | Rashid, Umer/C-9986-2011; Ashfaq, MuhammadZeeshan/LZG-8403-2025 | 57356994100; 15519923500; 7202035694; 16031556400; 59951845000; 57216926904; 57218944946; 59776428500; 57788334800; 57212448158; 57200522309; 57191375873 | amnaashfaq9@yahoo.com;raziyaanalyst@uaf.edu.pk;hygong@email.sdu.edu.cn;umer.rashid@upm.edu.my;saima_bashir03@yahoo.com;shafiq.urrehman@uaf.edu.pk;2015ag847@uaf.edu.pk;muhammadadil507@gmail.com;nayabzeeshan7863@gmail.com;zee4194202@gmail.com;fharthi@ksu.edu.sa;elham.ghasemi.k@gmail.com;dr.umer.rashid@gmail.com; | POLYMERS | POLYMERS-BASEL | 2073-4360 | 14 | 13 | SCIE | POLYMER SCIENCE | 2022 | 5 | 18.0 | 0.67 | 2025-06-25 | 6 | 9 | TiO2 nanocomposite (TiO2 NC); biomass; biochar; green synthesis; kinetic model; equilibrium model | TIO2 NANOPARTICLES; GREEN SYNTHESIS; HEAVY-METALS; PYROLYSIS; REMOVAL; PB(II); PEELS; WATER | biochar; biomass; equilibrium model; green synthesis; kinetic model; TiO<sub>2</sub> nanocomposite (TiO<sub>2</sub> NC) | Adsorption; Chromium compounds; Fruits; Isotherms; Kinetic theory; Nanocomposites; Synthesis (chemical); TiO2 nanoparticles; Agro-wastes; Banana peels; Biochar; Biosorbents; Equilibrium modelling; Green synthesis; Kinetic models; Potato peels; Response-surface methodology; TiO2 nanocomposite; Titanium dioxide | English | 2022 | 2022-07 | 10.3390/polym14132644 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Fast, Localized, and Low-Energy Consumption Self-Healing of Automotive Clearcoats Using a Photothermal Effect Triggered by NIR Radiation | Dynamic polymer networks containing photothermal materials have been reported to demonstrate highly efficient intrinsic self-healing under irradiation. In particular, organic near-infrared-absorbing ionic salts, such as diimmonium dyes, function as transparent polymer heaters and can enhance the self-healing properties of clearcoats. In this study, we designed a self-healing automotive clearcoat with a reversible polymer network based on acryl polyol (AP) and dynamic hindered urea (HU) bonds and introduced N-butyl-substituted diimmonium borate dye (DID) as a photothermal dye. To optimize the self-healing efficiency of the clearcoat and its transparency in the visible light region, the effects of the presence or absence of dynamic HU bonds and the concentration of the photothermal dye were precisely investigated. For a polymer system containing HU with 0.1 wt % DID (AP/HU-DID₀.₁), the transparent automotive clearcoat was heated to ∼70 °C under focused sunlight irradiation and exhibited excellent (∼100% healing efficiency) and fast (<30 s) scratch-healing performance compared with a commercial automotive clearcoat. In addition, this photothermal effect-based self-healing clearcoat exhibited outstanding transparency (over 95%) and has a strong advantage with respect to energy consumption because it enables faster and more localized healing compared with thermal healing processes that require heating the entire product. © 2022 American Chemical Society. | Son, Da Hae; Bae, Hyoung Eun; Bae, Mi Ju; Lee, Sang-Ho; Cheong, In Woo; Il Park, Young Il; Jeong, Ji-Eun; Kim, Jin Chul | Department of Specialty Chemicals, Division of Specialty and Bio-Based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-Based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-Based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-Based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; School of Applied Chemistry, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-Based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-Based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea; Department of Specialty Chemicals, Division of Specialty and Bio-Based Chemicals Technology, Korea Research Institute of Chemical Technology (KRICT), Ulsan, 44412, South Korea | 57223202891; 57578621900; 57578177000; 58743026900; 7006733373; 58940566100; 56330436800; 56805502600 | inwoo@knu.ac.kr;ypark@krict.re.kr;jieunj@krict.re.kr;jckim81@krict.re.kr; | ACS Applied Polymer Materials | ACS APPL POLYM MATER | 2637-6105 | 2637-6105 | 4 | 5 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;POLYMER SCIENCE | 2022 | 5 | 18.0 | 2.37 | 2025-06-25 | 27 | automotive clearcoat; dynamic hindered urea bond; dynamic polymer network; intrinsic self-healing; NIR absorption; photo-thermal effect; scratch-healing coating | Energy utilization; Infrared devices; Irradiation; Low power electronics; Metabolism; Self-healing materials; Transparency; Automotive clearcoat; Automotives; Clearcoat; Dynamic hindered urea bond; Dynamic polymer network; Intrinsic self-healing; NIR absorptions; Photo-thermal; Photo-thermal effect; Polymer networks; Scratch healing; Scratch-healing coating; Self-healing; Urea | English | Final | 2022 | 10.1021/acsapm.1c01768 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Article | Grafted Semiflexible Nunchucks with a Magnetic Bead Attached to the Free End | Semiflexible nunchucks are block copolymers, which consist of two long blocks of high bending stiffness jointed together by a short block of low bending stiffness. Semiflexible nunchucks that consist of two DNA nanorods jointed by a short segment of double-stranded (ds) DNA and confined in two dimensions have been used in recent experiments by Fygenson and coworkers as a tool to magnify the bending fluctuations of the linking dsDNA, which in turn are used to deduce the persistence length of dsDNA. In a recent theoretical analysis, we showed that in a semiflexible nunchuck with one end grafted, the fluctuations of the position of the free end that is transverse to the grafting direction exhibit a pronounced bimodality, provided that the bending stiffness of the hinge is not very large. In this article, we theoretically analyse a grafted semiflexible nunchuck with a magnetic bead attached to its free end. We show that a transverse magnetic field induces an asymmetry in the bimodal distribution of the transverse fluctuations of the free end. This asymmetry is very sensitive to interactions with a magnetic field and, in principle, could be used in magnetometry (the measurement of a magnetic field or the magnetic moment of the bead). We also investigate how the response of the bimodal distribution of the transverse fluctuations of the free end to a magnetic field depends on the bending stiffness of the nunchuck hinge. In addition, we analyse the closely related systems of a single filament and two filaments jointed at a kink point with one end grafted and the other end attached to a magnetic bead. | Razbin, Mohammadhosein; Benetatos, Panayotis | Amirkabir Univ Technol, Dept Energy Engn & Phys, Tehran 14588, Iran; Kyungpook Natl Univ, Dept Phys, 80 Daehakro,Bukgu, Daegu 41566, South Korea | Benetatos, Panayotis/AAT-5957-2021; Razbin, Mohammadhosein/P-1405-2019; Razbin, Dr. rer. nat.
