Herein, cryo-spun drying strategy is proposed to fabricate the thermoplastic polyurethane (TPU) fiber with anisotropic conductive networks (ACN@TPU fiber). Benefiting from the excellent mechanical properties of TPU, and the excellent interface among TPU, silver nanoparticles (AgNPs) and polyvinyl alcohol (PVA), the prepared ACN@TPU fiber exhibits an outstanding mechanical performance.

Furthermore, mathematical model based on AgNPs is established and the resistance calculation equation is derived, with a highly matched fitting and experimental results (<span>(R^{2})</span> = 0.998). As a conceptual demonstration, the ACN@TPU fiber sensor is worn on a mannequin to accurately and instantly detect movements.

This study proposes a facile fabrication process for Poly(vinylidene fluoride) (PVDF) nanofiber (NF) mats incorporating additive and nonadditive physical modifications. Patterned PVDF NF mats are prepared by electrospinning using a metal mesh as the NF collector. As a negative triboelectric material, the TENG with the patterned PVDF NF mat exhibits superior performance owing to the engineered morphology of the contact layer. PVDF is crucial in TENGs owing to its superior ferroelectric properties and surface charge density when combined with specific electroceramics. Hence, the synergy of the physical modification methods is achieved by incorporating BaTiO<sub>3</sub> (BTO) nanoparticles (NPs) into the PVDF. By functionalizing BTO NPs with polydopamine, the TENG performance is further improved owing to the enhanced dispersion of NPs and improved crystallinity of the PVDF chains. Utilizing large NPs produces a nanopatterning effect on the NF surface, thereby resulting in the hierarchical structure of the NF mats. The source of the voltage signals from the TENG is analyzed using fast Fourier transform.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"6 6","pages":"1910 - 1926"},"PeriodicalIF":17.2,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
