主 题：electrospinning strain sensor electrothermal/photothermal conversion CuS wearable fabric
摘 要：Electrospun nanofibers with highly efficient photothermal/electrothermal performance are extremely popular because of their great potential in wearable heaters.However,the lack of necessary wearable properties such as high mechanical strength and quick response of electrospun micro/nanofibers seriously affects their practical application.In this work,a technical route combining electrospinning and surface modification technology is proposed.The 3-triethoxysilylpropylamine-polyacrylonitrile@copper sulfide(K-PAN@CuS)composite fabric was achieved by modifying the original electrospinning PAN fiber and subsequently loading CuS nanoparticles.The results show that the break strength of the K-PAN@CuS fabric was increased by 10 times compared to that of the original PAN@CuS fabric.Furthermore,the saturated temperature of the K-PAN@CuS fabric heater could reach 116℃within 15 s at a relatively low voltage of 3 V and 120.3℃within 10 s under an infrared therapy lamp(100 W).In addition,due to its excellent conductivity,such a unique structural design enables the fiber to be closely attached to the human skin and helps to monitor human movements.This K-PAN@CuS fabric shows great potential in wearable heaters,hyperthermia,all-weather thermal management,and in vitro physical therapy.
