NOVELTY - The method for modification of graphene surface covalent bond, involves adding graphene powder to dimethylformamide, ultrasonically processing for 1 hour, adding methyl methacrylate and N,N'-dicyclohexylcarbodiimide, heating at 90 degrees C and stirring under nitrogen for 48 hours, terminating the reaction, suction filtering the reaction solution using PTFE filter with a pore size of 0.22 mu m, repeatedly washing with excess ethanol and drying in vacuum oven at room temperature. USE - Method for modification of graphene surface covalent bond. ADVANTAGE - The method enables modification of graphene surface covalent bond with excellent antistatic effect.
