▎ 摘　　要

NOVELTY - Preparation of composite material involves dispersing graphene in anti-solvent to obtain graphene dispersion, mixing graphene dispersion with resin solution to precipitate resin microspheres to obtain solid-liquid mixture, filtering solid-liquid mixture and drying. USE - Preparation of composite material (claimed). ADVANTAGE - The resin microspheres uniformly adhere to surface of graphene, thereby achieving excellent dispersion between graphene and resin, and avoiding phenomenon of graphene agglomeration, and maximally exerting conductivity of graphene in resin matrix. The composite material of graphene and resin has excellent performance and is prepared by simple process with simple equipment requirements.
