▎ 摘　　要

Graphene has attracted considerable attention as anti-corrosion material due to its peculiar two-dimensional nanostructure and superior physicochemical properties. Graphene nanosheets can be inde-pendently or concertedly applied as the barriers against metal corrosion in the form of thin films, layered structures, or composites. Numerous attempts have been made to establish the correlation between the nanoscale structure and macroscale performance of graphene. In that regard, experimental and compu-tational methods, such as quantum chemistry and molecular simulation, allow one to gain insight into the anti-corrosion mechanisms of graphene-related coatings. This review summarizes up-to-date knowl-edge about pure graphene and graphene-based composite coatings, including cathodic protection and self-healing coatings. Particular attention is paid to the structure-property relationship and anti-corrosion mechanisms in these systems. Finally, the shared and distinct role of graphene in various coat-ings and their prospects for future research are discussed as well. (c) 2021 Elsevier Ltd. All rights reserved.
