Problems solved by technology

Because the cyano group on the polyacrylonitrile fiber can complex with copper ions, the fiber has conductivity; the surface of ordinary glass fiber lacks groups that complex with copper ions, and the conductive substance cannot complex with the fiber, so it affects The adsorption and adsorption fastness of fibers to metal sulfides are affected, so it is impossible to obtain fibers with excellent electrical conductivity.

Abstract

The invention discloses a method for preparing electrically conductive glass fibers by adopting plasma-assisted preprocessing. The method comprises the following steps: firstly, cleaned glass fibers are subjected to vacuum plasma processing, and surface hydroxylation of the glass fibers is realized; then the glass fibers are soaked in a silk fibroin solution and subjected to crosslinking through glutaraldehyde, so that a firm silk fibroin layer is formed on the surfaces of the glass fibers; finally, copper sulfate pentahydrate and sodium thiosulfate are taken as raw materials to produce copper(I) sulfide on the surfaces of the glass fibers with a chemical reaction method. The method has the advantages that adsorption of metal sulfide on the surfaces of the glass fibers is improved effectively, the interfacial adhesion is strong, preparation process conditions are easy to implement, the cost is saved, the electrical conductivity of the fibers are excellent and the like.
