The core\/shell-TrFE\/CTFE membrane discloses a more prominent mechanical anisotropy between the revolving direction (RD) and cross direction (CD) associated with a higher tensile modulus of 26.9 MPa and good strength-ductility balance, beneficial from a better degree of nanofiber alignment, the increased density, and C-F bonding. The interfacial coupling between the terpolymer P(VDF-TrFE-CTFE) and copolymer P(VDF-TrFE) is responsible for comparable full-frequency dielectric responses between the core\/shell-TrFE\/CTFE and pristine terpolymer. Moreover, an impressive piezoelectric coefficient up to 50.5 pm\/V is achieved in the core\/shell-TrFE\/CTFE composite structure. Our findings corroborate the promising approach of coaxial electrospinning in efficiently tuning mechanical and electrical performances of the electrospun core\/shell composite nanofiber membranes-based electroactive polymers (EAPs) actuators as artificial muscle implants.<\/jats:p>","DOI":"10.3390\/ijms22094639","type":"journal-article","created":{"date-parts":[[2021,4,28]],"date-time":"2021-04-28T10:41:58Z","timestamp":1619606518000},"page":"4639","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Tunable Mechanical and Electrical Properties of Coaxial Electrospun Composite Nanofibers of P(VDF-TrFE) and P(VDF-TrFE-CTFE)"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5129-0771","authenticated-orcid":false,"given":"Tu-Ngoc","family":"Lam","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, National Yang Ming Chiao Tung University, Hsinchu 30013, Taiwan"},{"name":"Department of Physics, College of Education, Can Tho University, Can Tho City 900000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia-Yin","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Yang Ming Chiao Tung University, Hsinchu 30013, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Po-Han","family":"Hsiao","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Yang Ming Chiao Tung University, Hsinchu 30013, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen-Ching","family":"Ko","sequence":"additional","affiliation":[{"name":"Central Region Campus, Industrial Technology Research Institute, Nantou County 54041, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8948-6988","authenticated-orcid":false,"given":"Yi-Jen","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Fiber and Composite Materials, Feng Chia University, Taichung 40724, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soo-Yeol","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Chungnam National University, Daejeon 34134, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jayant","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Indian Institute of Technology, New Delhi 110016, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4986-0661","authenticated-orcid":false,"given":"E-Wen","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, National Yang Ming Chiao Tung University, Hsinchu 30013, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5","DOI":"10.1007\/s42558-019-0005-1","article-title":"Electroactive polymer (EAP) actuators\u2014Background review","volume":"1","author":"Anderson","year":"2019","journal-title":"Mech.
