▎ 摘　　要

NOVELTY - Graphene composite material comprises matrix and graphene material. The graphene material is dispersed in matrix. The matrix is mineral powder. The graphene material exists in the form of powder or aggregate and is loaded with negative ionomer. The graphene composite material is a block porous structure with a pore diameter less than 10 microns. USE - The graphene composite material is used for fuel saving and vehicle protection (claimed). ADVANTAGE - The material improves fuel combustion efficiency and power output, reduces fuel consumption in one hundred kilometers after use, carbon deposition in automobile parts, exhaust gas emission and exhaust gas odor. The preparation avoids agglomeration of graphene, maintains high infrared radiation rate, increases the release amount of negative ions, shortens the release reaction time, reduces production cost and the surface roughness and friction coefficient of the product, enhances the wear resistance of the product.
