▎ 摘　　要

NOVELTY - Preparing polymer composite material containing graphene comprises taking graphene and polymer and evenly dispersing in a solvent, then adding an another solvent as precipitating agent to the mixed liquid, precipitating the polymer and graphene together for coating or covering the graphene to obtain polymer/grapheme composite material. USE - The method is useful for preparing polymer composite material containing graphene (claimed). ADVANTAGE - The method has low cost and simple operation, and is easy-to process.
