高导电柔性PDA/PPy加热棉织物的制备及性能研究
Preparation and Performance Study of Highly Conductive Flexible PDA/PPy Heated Cotton Fabrics
摘要
Abstract
With the rapid development of wearable devices,flexible electrically-heated fabrics have attracted significant attention due to their broad application prospects.However,widely-used conductive materials have obvious defects such as poor flexibility and uneven temperature distribution of metal materials and weak interfacial adhesion to textile substrates of conductive polymer polypyrrole(PPy).To address this critical bottleneck,in-spired by mussel foot proteins,polydopamine(PDA)was employed to modify cotton fabrics,and a PDA-PPy conductive layer on the cotton fabrics was constructed by using a simple in situ polymerization method.The ex-perimental results demonstrated that the prepared flexible electrically-heated fabrics possessed a relatively low sheet resistance(5.9 Ω)and excellent electrothermal response performance with good tunability,rapidly heating within just tens of seconds and reaching a steady-state temperature of 95.7℃under a low voltage of 5 V.Moreo-ver,the material exhibited outstanding heating-cooling cycle stability with only a 7.2%decrease in electrother-mal performance after 20 cycles and very low resistance change rate under various bending deformations.The study provided an effective solution to the interfacial adhesion issue between conductive polymers and substrates,and the developed composite showed significant application potential in the field of smart wearables.关键词
