Graphene has been extensively applied in metallic protection fields based on its extraordinary barrier property, large specific surface area, superlubrication, superhydrophobicity, and many other functional properties. However, two inescapable obstacles appear during the construction process of graphene-based composite coatings (GCCs) that impair the long-term protection performance of the obtained GCCs: 1) the uncontrolled distribution between graphene layers, and 2) the enfoldment of graphene sheets. Several approaches involve electric field-induced alignment, magnetic field-induced alignment, unfolding, and nacre-inspired synergistic strategy have been developed to address these obstacles in recent years, and brought about superior GCCs.

Perspectives for preparing high-performance and multifunctional GCCs

A new MiniReview summarises and compares these effective approaches for fabricating high-performance GCCs, featuring the relationship between the interface structure and corrosion protection performance. Also, the fabrication processes and creating broad-spectrum mechanical, thermal, electrical, antibacterial, self-healing, and anti-wear performance are discussed. Finally, perspectives for preparing high-performance and multifunctional GCCs were proposed.

The review has been published in Progress in Organic Coatings, Volume 178, May 2023.
