A recent publication presented an overview of the synthesis and application of graphene (G) for corrosion protection, and chemically modified graphene oxide (GO) emerged as new class of corrosion inhibitors, due to their excellent hydrophobicity, chemical resistance, stability, high mechanical strength.

The article covers the synthesis of modified GO and their salient features as corrosion-resistant coatings and inhibitors, and explores the various covalent/ non-covalent approaches for the modification of graphene and GO. An outline of the different types of single and multi-layer graphene-based anticorrosion coatings is also discussed, as is an overview of the literature on the chemically modified GO-based aqueous corrosion inhibitors focused on the different mechanisms underlying the corrosion protection behaviour. Finally, the research prospects on some newly emerging 2D material-based corrosion protecting agents is also explored.

This overview was published in Progress in Organic Coatings, Volume 147, October 2020.
