In this paper, we demonstrate highly conductive and stretchable fiber interconnections for electronic textiles (e-textiles) using dry-spun carbon nanotube (CNT) fibers modified with ionic liquid (IL)/poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) copolymer composite. By adopting direct infiltration of CNT fibers with a mixture of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide and PVDF-HFP, mechanical properties such as stretchability, maximum load and strain were significantly improved while minimizing the reduction in electrical conductivity. Such IL/PVDF modified CNT fibers (hybrid CNT fibers) exhibited electrical conductivity up to ∼1300 S/cm, with maximum load and strain values of 0.84 N and 35.7%, respectively. Using hybrid-CNT fibers, we demonstrated highly stretchable and electrically stable fiber interconnections for e-textiles by optimizing the interconnection pattern design. Particularly, by adopting a serpentine pattern, stretchability up to ∼70% and resistance variation of ∼2.7% at a tensile strain of 40% were achieved.

使用离子液体/聚偏二氟乙烯共聚物复合材料改性的干纺碳纳米管纤维实现高导电性和可拉伸性的纤维互连

在本文中,我们演示了使用经离子液体(IL)/聚偏二氟乙烯-共六氟丙烯(PVDF-)改性的干纺碳纳米管(CNT)纤维,用于电子纺织品(e-textile)的高导电性和可拉伸纤维互连。 HFP)共聚物复合材料。通过采用1-丁基-3-甲基咪唑双(三氟甲基磺酰基)酰亚胺和PVDF-HFP的混合物直接渗透CNT纤维,可显着改善机械性能,例如拉伸性,最大载荷和应变,同时最大程度地降低电导率的降低。此类IL / PVDF改性的CNT纤维(混合CNT纤维)显示出高达1300 S / cm的电导率,最大载荷和应变值分别为0.84 N和35.7%。使用混合CNT纤维,通过优化互连图案设计,我们展示了用于电子纺织的高度可拉伸且电稳定的纤维互连。特别是,通过采用蛇形图案,在拉伸应变为40%时可实现高达70%的可拉伸性和2.7%的电阻变化。
