Abstract
Disclosed are a graphene material and a manufacturing method thereof. A high molecule powder material is uniformly mixed with a blend of carbon black and graphene to form a material mixture. An electrostatic spraying operation is conducted by using an electrostatic spray gun to spray the material mixture of the high molecule powder material, carbon black, and graphene to a surface of a substrate so as to form a graphene coating layer such that the substrate supports the graphene coating layer. The high molecule powder material is at least 10 grains and the blended carbon black and graphene takes weight percentage of 1-10%. Carbon black is distributed in graphene so that mutual contact between carbon black and graphene and material properties of carbon black that show high conductivity makes electrical charges contained in the graphene material easy to move.
