▎ 摘　　要

NOVELTY - Producing modified graphene-based polymer material comprises (i) mixing graphene, polymethyl methacrylate and absolute ethanol, filtering to obtain modified graphene, (ii) mixing modified graphene, methacrylic acid, polystyrene, N,N-dimethylformamide, polylactic acid and ethylene glycol to obtain mixed solution M, and subjecting mixed solution to copolymer plate by thermoforming, and (iii) adding copolymer plate into liquid resin matrix to obtain mixed solution N, thermoforming mixed solution N to obtain modified graphene-based polymer material. USE - The method is useful for producing modified graphene-based polymer material (claimed). ADVANTAGE - The material has poor dispersibility in resin, easy agglomeration, poor compatibility with resin and excellent mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for modified graphene-based polymer material obtained by above method.
