▎ 摘　　要

NOVELTY - A functionalized graphene comprises graphene oxide and epoxidized polymer monomer at mass ratio of 100:10-500. The epoxidized polymer monomer is epoxidized polymer monomer that contains benzene ring, ether bond, hydroxyl group, and/or amine group. USE - Functionalized graphene. ADVANTAGE - The method avoids the use of complicated reaction process conditions and large amount of organic solvent, can precisely regulate mass ratio of epoxidized polymer monomer and graphene oxide, and has simple operation steps. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the functionalized graphene comprising adding oxidized graphene dispersion to epoxidized polymer monomer at room temperature, mixing for 0.5-10 hours, and drying.
