NOVELTY - This utility new type claims a multifunctional graphene nano coating structure, comprising a substrate (1) from bottom to top, a bottom paint (2), middle layer paint (3) and net-like graphene surface (4); the substrate (1) is made of tinplate iron or ABS plastic plate, it has good adhesive force; the bottom paint (2) adopts aqueous acrylic resin layer, strong adhesion, can be well attached on the substrate, cheap and environment-friendly; the middle paint layer (3) is made of sulfonic acid type aqueous polyurethane resin layer. the bottom paint (2) with good adhesion, attached by electrostatic adsorption effect and between network-shaped graphene layer (4). The utility model type has advantages, it not only has simple structure, but also has graphene does not adopt the resin blend, but solely as the surface, effectively avoiding agglomeration of the graphene, and uniformly distributed on the coating surface, the coating structure has excellent antistatic property and outstanding thermal conductivity and electrical conductivity and high strength.
