▎ 摘  要

NOVELTY - Preparing graphene oxide grafted fluoropolymer by click using chemical synthesis comprises (i) preparing graphene oxide by using a modified Hummer's method, (ii) adding the graphene oxide obtained in the step (i) into an anhydrous solvent, ultrasonically dispersing under stirring conditions, adding propiolic acid, 4-dimethylaminopyridine and dicyclohexylcarbodiimide, reacting at room temperature, filtering, drying in vacuum and obtaining oxy graphene having an alkynyl group, (iii) obtaining an azide group fluoropolymer and (iv) ultrasonically dispersing the alkynyl-containing graphene oxide obtained in the step (ii) and the azide-containing fluoropolymer obtained in the step (3) are in the solvent D, adding into the flask, stirring the reaction by a copper catalyst, stirring at room temperature under nitrogen atmosphere and washing. USE - The method is useful for preparing graphene oxide grafted fluoropolymer by click using chemical synthesis. DETAILED DESCRIPTION - Preparing graphene oxide grafted fluoropolymer by click using chemical synthesis comprises (i) preparing graphene oxide by using a modified Hummer's method, (ii) adding the graphene oxide obtained in the step (i) into an anhydrous solvent, ultrasonically dispersing under stirring conditions, adding propiolic acid, 4-dimethylaminopyridine and dicyclohexylcarbodiimide, reacting at room temperature, filtering, drying in vacuum and obtaining oxy graphene having an alkynyl group, (iii) adding the azide of the fluoropolymer containing a fluorine-containing monomer, perfluoroiodohexane as a chain transfer agent, initiator and a solvent A, carrying out radical polymerization, reacting and drying to obtain an iodine-containing fluoropolymer, adding the obtained iodofluoropolymer and sodium azide into the flask, solvent B, stirring the mixture at room temperature, reacting, precipitating the solvent C and drying the precipitate in a vacuum oven to obtain an azide group fluoropolymer and (iv) ultrasonically dispersing the alkynyl-containing graphene oxide obtained in the step (ii) and the azide-containing fluoropolymer obtained in the step (3) are in the solvent D, adding into the flask, stirring the reaction by a copper catalyst, stirring at room temperature under nitrogen atmosphere and washing.
