A Brief Review of Noncovalently Modified Graphene Reinforced Anticorrosion Organic Coatings

Graphene has been widely demonstrated to significantly improve the anticorrosion properties of organic coatings, but much of the research has focused on covalently modified graphene approaches, and research on noncovalently modified graphene-enhanced organic coatings is relatively lacking. This article reviews the latest progress in the development of noncovalently modified graphene-based organic coatings for corrosion protection. It delves into diverse strategies for graphene integration via noncovalent interactions, including π-π stacking, hydrogen bonding, and electrostatic forces. This review assessed the influence of graphene on the anticorrosive efficacy, mechanical robustness, and longevity of the coatings. Additionally, it clarifies the corrosion inhibition mechanisms of graphene-modified coatings. This paper concludes by identifying the challenges currently facing this area of research and outlining a potential trajectory for future development.
