摘要

本工作采用化学原位聚合法，在预拉伸聚氨酯(PU)纤维基体上成功构筑了高度有序的螺纹结构聚吡咯(PPy)层. 得益于该特殊结构，所制得的核壳聚吡咯/聚氨酯(PPy@PU)复合导电纤维，克服了PPy薄膜的脆性，展现出良好的柔性和可拉伸性，在200%应变下，结构完整性依然可以恢复良好. 优化后的复合纤维作为可穿戴应变传感器，表现出高灵敏度(GF约为12.4@200%)、快速响应(500 mm/min)及优异耐久性(100%应变下200次循环). 此外，基于PPy@PU设计的可穿戴应变传感器可满足不同的人体运动检测需求(如手指弯曲和肘部伸展)，在可穿戴电子和智能纤维领域具有很好的应用潜力.

Abstract

A novel thread-type core-shell polypyrrole@polyurethane (PPy@PU) fiber was fabricated

via in situ

polymerization of PPy on pre-stretched PU fiber

and applied as a durable

flexible

stretchable

conductive strain sensor for the first time. Benefiting from the highly ordered continuous stretchable structure

thread-type core-shell structure can effectively buffer the dramatic deformation and maintain the structure integrity of PPy@PU fiber

resulting in stable conductivity during the stretching/releasing cycles. The variations in morphology and chemical structures

stretchability

and conductivity as well as the sensitivity of resistance change under stretching cycles were investigated. The optimized PPy@PU fiber presents advantages of large detecting strain up to 200%

high gauge factor of about 12.4 at 200%

and can detect changes as fast as 500 mm/min

long durability of 200 cycling times. Furthermore

the advantages of thread PPy@P

U fiber were then used to construct a prototype of wearable sensor to detect finger's bending and elbow's extension which exhibited its great potential applications as wearable devices and smart fabrics.
