BIOMEMBRANE ELECTRODE MATERIAL BASED ON SPECIAL-SHAPED CARBON FIBER, AND PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

Provided are a biomembrane electrode material based on special-shaped carbon fiber, and a preparation method therefor and the use thereof. The biomembrane electrode material comprises a special-shaped cross-section carbon fiber fabric electrode substrate and a biomembrane loaded on the electrode substrate. The special-shaped cross-section carbon fiber fabric electrode substrate comprises a special-shaped cross-section carbon fiber fabric, and graphene and polypyrrole loaded on the surface of the fabric and in voids of carbon fibers, wherein the polypyrrole is loaded on the surface of the graphene and forms polypyrrole nanowires, which form a three-dimensional nano-conductive network structure. The use of the special-shaped cross-section carbon fiber fabric as an electrode loading matrix can increase the specific surface area of the carbon fiber fabric. In addition, the voids of the special-shaped cross-section are in communication with each other, such that a void network structure is formed. When graphene and polypyrrole are loaded on the surface and in the voids of the fabric, a three-dimensional conductive network structure can be formed, and the problem of a reduced biomembrane performance caused by the antimicrobial effect of graphene can be overcome. The use thereof in organic wastewater treatment has the characteristics of a high current density and a high degradation rate.
