Abstract

The invention provides a silver-plated conductive fabric and a preparation method and application thereof, and belongs to the technical field of conductive fabric materials. The silver-plated conductive fabric provided by the invention comprises a sulfydryl modified fabric and a composite conductive silver layer positioned on the surface of the sulfydryl modified fabric, the composite conductive silver layer comprises a plurality of silver layers and sulfhydryl compound adsorption layers which are alternately stacked; the bottom layer and the surface layer of the composite conductive silver layer are silver layers; and the sulfydryl compound adsorption layer is formed by a sulfydryl-containing auxiliary reducing agent. According to the invention, the sulfydryl modified fabric and the silver layer are bonded through chemical bonds, so that the bonding strength of the sulfydryl modified fabric and the silver layer is high; the silver layers are connected through the sulfydryl compound adsorption layer, sulfydryl in the sulfydryl compound adsorption layer can form a stable silver-sulfydryl complex with silver, so that the binding force between the silver layers is very strong, and then the washing resistance of the conductive fabric is remarkably improved; and the silver layer endows the silver-plated conductive fabric with excellent conductivity.

Description

Technical field [0001] The present invention relates to the technical field of conductive fabric materials, and more particularly to a silver-plated conductive fabric and a preparation method thereof. Background technique [0002] The intelligent wear costume is multiferous as an electrode material, which can be used as a collection transfer of an electromechanical electrical signal, and a human body is converted into an electrical signal, and the human movement is perceived, and the electrode of the friction generator is used for energy acquisition, etc. . Therefore, fabric electrode materials have important uses in intelligent wear garments. The conductive fabric as an electrode material is typically in a textile as a substrate, and it has electrically conductive properties by composite with a conductive material such as a metal. However, during the use of smart wear costumes, water washing, etc. will seriously reduce the conductive properties of the conductive fabric, which af...
