▎ 摘　　要

NOVELTY - Preparation of graphene composite particles with core-shell structure comprises mixing graphene in organic solvent, mixing emulsifier in deionized water, mixing ethyl cellulose and epoxy resin with organic solvent, adding graphene solution, mixing to oil phase solution, mixing, adding oil phase solution with graphene, mixing, volatilizing organic solvent, mixing, adding oil phase solution to aqueous phase solution, volatilizing organic solvent, mixing until ethyl cellulose solidifies, filtering composite particles through filter cloth, washing with deionized water and placing in freeze-drying oven for drying treatment. USE - The method is used for preparation of graphene composite particles with core-shell structure. ADVANTAGE - The composite particles have same particle size. The graphene does not easily fall off and has good sphericity and fluidity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing the structure of the composite particle of a preparation method of core-shell structure graphene composite particle. Epoxy resin core material (1) Graphene cellulose mixed layer (3)
