PANI particles were uniformly distributed within the matrix and micropores formed by the phase separation of PES, which prevented PANI particles aggregation and facilitated the formation of continuous ion transport channels. 118532 Corpus ID: 264322494; Wet spinning of multi-walled carbon nanotube fibers @article{Im2023WetSO, title={Wet spinning of multi-walled carbon nanotube fibers}, author={Jaegyun Im and Yun Ho Jeong and Min Chan Kim and Daehan Oh and Jeonghyun Son and Kyu Hyun and Beomjin Jeong and Seungki Hong and Jaegeun Lee}, journal={Carbon}, year={2023}, url={https://api Oct 13, 2023 · Floating catalysis chemical vapor deposition (FCCVD) direct spinning process is an attractive method for fabrication of carbon nanotube fibers (CNTFs). 1220 www. 1. reported a composite fiber with highly enhanced toughness by hybrid the carbon nanotubes (CNTs) with graphene [16, 17]. Jul 4, 2019 · Here, we demonstrate the feasibility of a highly-efficient and potentially-continuous fiber-spinning method to produce high-performance carbon nanotube (CNT) fiber (CNTF). Jun 20, 2024 · Three spinning methods are used to fabricate CNTFs, including wet spinning (14, 15), vertically aligned array spinning , and direct aerogel spinning . To this end, materials for the CNT/PVDF fiber were selected, and a dope solution was prepared using MWNT, PVDF, and dimethylacetamide (DMAc). reported electrically conductive fibers prepared by wet-spinning 40 wt% multiwalled nanotubes (MWNTs) in polyvinyl alcohol; Su et al. This composite fiber exhibits excellent actuation performance, including high output stress and rapid response, surpassing most conventional shape memory polymer Jun 12, 2024 · DOI: 10. developed electrically conductive fibers with high elasticity using the wet spinning of Abstract. Wet-spinning is a broadly utilized commercial technique for high-performance fiber manufacturing. Here, we explored the surface characteristics of carbon nanotubes (CNTs) that are advantageous for the properties of CNTFs produced by wet spinning, using sodium cholate as a surfactant.
