▎ 摘　　要

NOVELTY - Graphene/epoxy resin conductive coating with gradient concentration, is claimed. The graphene concentration of each continuous layer in the coating can be adjusted and controlled to form a composite system with gradient concentration. The graphene in each concentration gradient layer is dispersed in the epoxy resin matrix and forming a micro cross-linked structure. USE - Used as graphene/epoxy resin conductive coating with gradient concentration ADVANTAGE - The coating: has good mechanical property, excellent conductivity and electro-thermal performance and is convenient and easy to operate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene/epoxy resin conductive coating with gradient concentration comprising providing a layer sheet grapheme and providing a dispersible epoxy resin, dispersing the layer sheet graphene in the epoxy resin, layered coating co-curing to form a conductive coating with gradient concentration, where the concentration gradient layer number of the conductive coating is more than two layers and has a micro cross-linked structure.
