▎ 摘　　要

NOVELTY - Preparing tungsten carbide/graphene composite material involves dispersing the tungsten source and the aromatic polyimide precursor in a solvent to obtain a uniformly dispersed mixed solution, coating the mixed solution on the surface of the substrate, drying to remove the solvent, heating in a protective atmosphere to raise the temperature to 60-300℃ to make the aromatic polyimide precursor amidation reaction, and obtaining a polymer film compounded with tungsten source on the surface of the substrate. The polymer film with a tungsten source is irradiated with a laser in an air atmosphere. The polymer film with a tungsten source is synchronously induced to form product. USE - Method for preparing tungsten carbide/graphene composite material. ADVANTAGE - The method has a high crystallization quality, high conductive capability, which is good for the transmission of the electronic in the electrochemical reaction process, excellent performance, good application prospect in the field of electro-catalytic material, provides a carrier with high specific surface area for tungsten carbide nano particles, and effectively suppresses the agglomeration of tungsten carbide, which is good for soaking electrolyte in electrochemical process, to improve the electrochemical performance.
