Graphene-based Coatings - A Corrosion Inhibiting Comrade

Abstract

Corrosion has been an intense problem the industry has faced since the industrial revolution in the 18th century. As a result, the protection of the machine body from corrosion-causing environmental factors has been a crucial topic of interest of various researchers for many decades. To improve the machine’s service life by inhibiting corrosion, graphene emerged as a revolutionary discovery. The main focus of this paper is concerned with anticorrosive coating derived from graphene and its derivatives. Graphene became evident as a revolutionary material because of its excellent properties. It has been observed that graphene coating has a more excellent corrosion inhibiting effect than a conventional coating. We have briefly discussed various manufacturing methods of graphene and graphene oxide. Industrial manufacturing of graphene is done by chemical vapor deposition. Recent studies reveal that graphene has turned out to be acceptable material for the preparation of polymer composites. Graphene-based polymer composite coatings have superior properties to regular graphene coatings and better corrosion inhibiting performance. These intriguing properties have inspired the research on hybrid graphene polymer composite materials.
