Application of graphene in metal corrosion protection

Abstract

Single-layer defect-free graphene has excellent shielding performance and can prevent corrosion factors such as oxygen and water molecules from reaching the surface of the metal matrix. Based on the great application potential of graphene in the field of metal corrosion protection, this paper systematically summarizes the graphene film protective coating, graphene/organic protective coating and graphene-conductive polymer/organic protective coating. The existing problems of graphene film and the uniform dispersion of graphene in organic coating are analyzed and introduced in detail, and the future development of graphene-based anti-corrosion coating is prospected.
