However, existing flexible conductive films struggle to maintain high conductivity while simultaneously ensuring excellent flexibility, hydrophobicity, and corrosion resistance, thereby limiting their use in harsh environments. In this paper, a novel method is proposed to fabricate flexible conductive films via centrifugal spinning to generate thermoplastic polyurethane (TPU) nanofiber substrates by employing carbon nanotubes (CNTs) and carbon nanofibers (CNFs) as conductive fillers. These fillers are anchored to the nanofibers through ultrasonic dispersion and impregnation techniques and subsequently modified with polydimethylsiloxane (PDMS). This study focuses on the effect of different ratios of CNTs to CNFs on the film properties. Research demonstrated that at a 1:1 ratio of CNTs to CNFs, with TPU at a 20% concentration and PDMS solution at 2 wt%, the conductive films crafted from these blended fillers exhibited outstanding performance, characterized by electrical conductivity (31.4 S\/m), elongation at break (217.5%), and tensile cycling stability (800 cycles at 20% strain). Furthermore, the nanofiber-based conductive films were tested by attaching them to various human body parts. The tests demonstrated that these films effectively respond to motion changes at the wrist, elbow joints, and chest cavity, underscoring their potential as core components in strain sensors.<\/jats:p>","DOI":"10.3390\/s24124026","type":"journal-article","created":{"date-parts":[[2024,6,21]],"date-time":"2024-06-21T03:44:49Z","timestamp":1718941489000},"page":"4026","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Preparation of CNT\/CNF\/PDMS\/TPU Nanofiber-Based Conductive Films Based on Centrifugal Spinning Method for Strain Sensors"],"prefix":"10.3390","volume":"24","author":[{"given":"Shunqi","family":"Mei","sequence":"first","affiliation":[{"name":"Hubei Digital Textile Equipment Key Laboratory, Wuhan Textile University, Wuhan 430073, China"},{"name":"The Advanced Textile Technology Innovation Center (Jianhu Laboratory), Shaoxing 312000, China"},{"name":"School of Mechanical & Electrical Engineering, Xi\u2019an Polytechnic University, Xi\u2019an 710048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-9991-2159","authenticated-orcid":false,"given":"Bin","family":"Xu","sequence":"additional","affiliation":[{"name":"Hubei Digital Textile Equipment Key Laboratory, Wuhan Textile University, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jitao","family":"Wan","sequence":"additional","affiliation":[{"name":"Hubei Digital Textile Equipment Key Laboratory, Wuhan Textile University, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jia","family":"Chen","sequence":"additional","affiliation":[{"name":"Hubei Digital Textile Equipment Key Laboratory, Wuhan Textile University, Wuhan 430073, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Liu, E., Cai, Z., Ye, Y., Zhou, M., Liao, H., and Yi, Y.
