▎ 摘  要

NOVELTY - A multiwall carbon nanotube is longitudinal cut by using oxidation, to obtain graphene nano belt. The obtained graphene nano belt is added into N,N-dimethylformamide, and ultrasonically dispersed, to obtain uniform and stable of graphene nano belt dispersion. The nano graphene oxide is added into the reactor with dispersion, and then methyl methacrylate and azo-bis-iso-butyrynitrile are added and heated. The product is poured into the methanol, centrifuged and separated, washed and dried in vacuum, to obtain polymethyl methacrylate-modified graphene nano belt. USE - Preparation of polymethyl methacrylate-modified graphene nano belt. ADVANTAGE - The polymethyl methacrylate-modified graphene nano belt is efficiently prepared with improved mechanical property, tensile strength and young's modulus.
