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 preparation method of conductive glass fibers with cuprous sulfide as a conductive layer and belongs to the field of preparation of composite conductive fibers. According to the method, firstly, glass fibers which are washed clean are subjected to hydroxylation treatment in a hydrochloric acid solution and soaked in a silk fibroin aqueous solution, crosslinking is performed through glutaraldehyde, and accordingly, firm silk fibroin layers are formed on surfaces of the glass fibers; finally, copper sulfate pentahydrate and sodium thiosulfate are taken as raw materials and subjected to a chemical reaction, and then cuprous sulfide is produced on surfaces of the glass fibers. With the adoption of the method, adsorption of metal sulfides on the surfaces of the glass fibers is effectively improved, the interface adhesion is high, and the method has the advantages that the preparation process condition is easy to guarantee, the cost is saved, the conductive performance of the fibers is excellent and the like.
