▎ 摘　　要

NOVELTY - Preparing surface-modified graphene comprises (i) adding graphene powder into dimethylformamide, performing ultrasound treatment after one hour, adding methyl methacrylate monomer and N, N'-dicyclohexylcarbodiimide, then heating at 90 degrees C and stirring under nitrogen for 48 hours, terminating reaction, suction filtering reaction solution using polytetrafluoroethylene filter having pore size of 0.22 mu m, repeatedly washing with excess ethanol, and drying in vacuum oven at room temperature to obtain methyl methacrylate-grafted graphene. USE - The method is useful for preparing surface-modified graphene. ADVANTAGE - The surface-modified graphene ensures excellent antistatic function of ultraviolet coating.
