Abstract

The invention relates to a method for preparing an indium-tin oxide / PDMS(polydimethylsiloxane) resin conducting material based on a textile template, which comprises the steps of: (1) preparing a precursor solution of an indium-tin oxide; (2) under a vacuumized environment, soaking a textile in the precursor solution, then taking out and drying, and calcining to obtain the indium-tin oxide conducting material; and (3) evenly mixing PDMS with a curing agent in a mass ratio of 10:1, then flatly laying the indium-tin oxide conducting material obtained in step (2) on the top of the mixture, curing at the temperature of 100 to 120 DEG C for 10 to 20min, and obtaining the indium-tin oxide / PDMS resin composite conducting material. The method provided by the invention has the advantages of simplepreparation process, low cost and easiness for realization of industrial production, and the prepared indium-tin oxide / PDMS resin composite flexible conducting material has the advantages of compact structure, fine electrical conductivity, fine foldable performance and broad market prospects.

Description

technical field [0001] The invention belongs to the field of preparation of conductive materials, in particular to a method for preparing indium tin oxide / PDMS resin conductive materials based on textile templates. Background technique [0002] In recent years, with the rapid development of information technology and optoelectronic products, new conductive materials have received more and more extensive research and attention. The research on transparent conductive oxide (TCO) is earlier, but it has attracted people's attention because of its excellent electrical conductivity, high chemical stability and good bonding performance with the substrate, especially in the field of electronics. Such as flat panel displays, sensors, dye-sensitized solar cells, etc. TCO materials mainly include SnO 2 Base, In 2 o 3 Various systems such as base and ZnO base, among which indium tin oxide (ITO) is the most representative. ITO is one of the most widely researched and applied transpa...
