摘要
PURPOSE: A method for modifying the surface of graphene oxide by using surface-initiated-polymerization based on the irradiation of electromagnetic waves is provided to shorten times required for surface modifying reaction. CONSTITUTION: A method for modifying the surface of graphene oxide includes the following: graphene oxide is introduced into an organic solvent and is dispersed by ultrasonic wave-based decomposition; the dispersed graphene oxide slurry is mixed with monomers and a catalyst; the mixture is introduced into an electromagnetic wave irradiating device; the mixture is irradiated with electromagnetic waves at a temperature between 80 and 120 degrees Celsius for 20 to 50 minutes to obtain graphene oxide-polymer nano-composite. The organic solvent is one selected from a group including toluene, dichloromethane, dimethyl sulfoxide, dimethyl formamide, tetrahydrofurane, acetone, diethyl ether, ethyl acetate, and hexane. The polymer is poly(benzyl vinyl chloride), poly(vinylidene chloride), or poly(vinyl chloride).
