Problems solved by technology

[0005] At present, domestic and foreign literature reports mainly use pre-prepared graphene to add to the polymer matrix to conduct research on the electrical conductivity. The common problem is that the dispersion of graphene is difficult to be guaranteed, and it is difficult to ensure the uniform dispersion of graphene in thermoplastic polymers. In situ reduction of graphene oxide in a matrix to obtain electrical conductivity is rarely reported

Abstract

The invention belongs to the technical field of nanocomposites, and particularly relates to a graphene / polyaryl ether sulfone ketone conductive film and a preparation method thereof. The method comprises the following steps: fully dispersing a certain amount of graphene oxide in a solvent by utilizing ultrasound to form a uniform stable solution, after mixing the uniform stable solution with a polyaryl ether sulfone ketone resin solution with a certain concentration, placing the mixed solution in a microwave generator for in-situ reduction of the graphene oxide, and then obtaining a polyaryl ether sulfone ketone film containing graphene by adopting a solution coating film forming process. The graphene / polyaryl ether sulfone ketone film prepared by the invention is excellent in electrical properties, uniform in dispersion of graphene and relatively high in mechanical strength, and is widely applied in multiple fields such as electromagnetic shielding, antistatic property and flexible sensors.
