多功能耐水导电纳米银装饰棉织物具有优异的焦耳加热性能和人体运动监测

Smart textiles have got increasing attention for potential application in personal thermal management, wearable human motion monitoring, and healthcare. However, it is still a challenge to prepare a multifunctional electronic textile with water-resistant, electro-thermal response, mechanical-sensitive performance, and antibacterial activities. Here, a multifunctional conductive cotton textile is fabricated by in-situ reduction silver nanoparticles(Ag NPs) on cotton fiber under the assistance of tannic acid, followed decorating with polydimethylsiloxane (PDMS). These obtained multifunctional textiles (cotton/TA/Ag NPs/PDMS textile) not only maintain the innate flexibility, and permeability characteristics of cotton textiles, but also exhibit rapid thermal response, outstanding long-time steady heating performance, and antifouling property. Furthermore, the cotton/TA/Ag NPs/PDMS textiles exhibit excellent strain sensing performance for potential human motions monitoring. Impressively, cotton/TA/Ag NPs/PDMS textiles show resistance to bacterial. Thus, this multifunctional cotton textile provides a new way for the study of the next generation of lightweight, portable, and wearable electronic textile devices.
