摘要：

The high conductivity of graphene (G) results in G-based composite coatings with unacceptable corrosion-promotion activity (CPA), which greatly limits their applications in metal protection. Herein, a bioinspired graphene-epoxy (B-G-EP) coating with nacre-like structure is constructed to investigate the interfacial structure-dependent anticorrosion of coatings. The results demonstrate that the highly aligned structure of B-G-EP resolves the contradiction between the anticorrosion capability and CPA of G, which breaks the limitation of the "blending rule" and provides insight into the preparation of high-performance G-based coatings through biomimetic strategies.
