A process for preparing a graphene-coated powder material, the process comprising: A) graphene powder and / or graphene oxide powder, powder material to be coated with graphene, and a polymerizable co-coating agent Dispersing in a first organic solvent to form a first organic solvent dispersion; B) mixing the first organic solvent dispersion with a second organic solvent and separating the precipitate after settling; And C) annealing the precipitate in an inert atmosphere to obtain a graphene-coated powdery material, wherein the polymerizable co-coating agent is soluble in the first organic solvent but insoluble in the second organic solvent. . The invention also relates to graphene-coated powdery materials produced by the process. |
