Graphene conducting material and preparation method thereof

Abstract

The invention discloses a graphene conducting material. The graphene conducting material is prepared from the following raw materials in parts by weight: 30 to 41 parts of graphene oxide, 20 to 30 parts of a conducting dispersion solution, 35 to 40 parts of aniline, 1 to 2 parts of ammonium persulfate, 0.4 to 1 part of melamine, 0.1 to 0.2 part of tert-butyl p-diphenol, 4 to 5 parts of diphenyl silanediol and 2 to 3 parts of calcium propionate. According to the graphene conducting material disclosed by the invention, various conducting substances, such as polyaniline, acetylene carbon black and graphene, are added; all the raw materials are blended and the graphene conducting material has very strong cooperatively enhanced conductivity; after the raw materials are treated by a method disclosed by the invention, the effects of stable finished products and efficient electric conduction are realized.

Description

technical field

[0001] The invention belongs to the field of graphene conductive materials, in particular to a graphene conductive material and a preparation method thereof. Background technique

[0002] The unique structure of graphene endows it with many excellent properties, such as mechanical properties, thermal properties, electrical properties and optical properties. In terms of mechanical properties, graphene is currently the material with the highest hardness and strength in the world. Its hardness is harder than diamond, its ultimate strength reaches 130GPa, and its tensile modulus reaches 1.01TPa, which is 300 times that of steel. Graphene undergoes certain functions. After chemical modification, its dissolution, dispersion and compatibility in different environments can be improved, and its research and application in different fields can be expanded. Because graphene has excellent mechanical, electrical, thermal and optical properties, after compounding with pol...
