Application of highly oriented two-dimensional materials in anti-corrosion coatings: a review and prospect

Abstract

Two-dimensional (2D) layered materials, represented by graphene/graphene oxide (GO) and Ti3C2Tx, are rapidly advancing in their application within anti-corrosion coatings. Their remarkable features, such as large specific surface area, adjustable structure and functionality, and diverse arrangement forms, endow them with vast potential as anti-corrosion materials. This paper, anchored in the highly oriented arrangement of 2D materials in coatings, provides an overview of the anti-corrosion potential of composite materials with ordered microstructures. It explores the dispersion and orientation of 2D materials in resin coating matrices under force field induction, electric field induction, and magnetic field induction. Additionally, it offers a detailed introduction to recent advances in the self-aligned arrangement of graphene/graphene oxide and Ti3C2Tx in resin coatings, focusing on their anti-corrosion applications and underlying mechanisms. Finally, the paper summarizes and anticipates the future prospects of directional distribution of 2D materials in the anti-corrosion field, aiming to provide new insights into the interface construction and performance regulation of these materials, and to inspire the development of high-performance anti-corrosion coatings with simple preparation processes and exceptional protective properties.
