Abstract

The invention provides a method for manufacturing an intelligent transparent and conductive fabric based on composite modification of nanoparticles and nanowires. The method comprises the following steps: putting ethylene glycol into polyvinylpyrrolidone of a high molecular weight, stirring violently till the polyvinylpyrrolidone is completely dissolved, adding copper chloride, sealing, performinga heating reaction, further adding a silver nitrate solution, shielding light, stirring violently, heating in an oven, and cleaning so as to obtain a mixed solution of silver nanowires and silver nanoparticles; putting a conductive polymer, silicon nanowires and graphene into the mixed solution of the silver nanowires and the silver nanoparticles, and uniformly mixing so as to obtain a transparent conductive solution; pretreating and cleaning the surface of a fabric, performing waterproof coating treatment, further coating the fabric with the transparent conductive solution, and finally performing surface treatment, namely spraying sodium borohydride, so as to obtain a transparent conductive coating modified fabric; adhering a Fe-N-C porous particle layer to the transparent conductive coating modified fabric, thereby obtaining the intelligent transparent and conductive fabric based on composite modification of nanoparticles and nanowires.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a method for preparing transparent and conductive intelligent textiles based on composite modification of nanoparticles and nanowires. Background technique [0002] Flexible transparent conductors are thin films that can both transmit light and conduct electricity in the visible light range. Traditional transparent conductors are mainly indium tin oxide, but their flexibility is poor, and indium resources are in short supply and high cost. It is difficult to meet the growing demand for flexible transparent conductors. . With the continuous development of science and technology, it has been found that carbon nanomaterials, metal nanomaterials, metal networks and conductive polymers can be used to prepare alternative flexible transparent conductor materials with low cost, convenient preparation and wide adaptability. There are a wide range of applications in ...
