A review on graphene-based polymer composite coatings for the corrosion protection of metals

Abstract Graphene-based coating is an emerging field that focuses on developing advanced coatings by exploiting new generation materials with superior properties. Researchers are striving to develop coatings that are cost-effective, easy to prepare and highly effective by integrating graphene with a wide range of suitable materials for surface protection applications. In this critical review, different types of high performing graphene-based polymer composite coatings have been described for anticorrosion application. An in-depth survey on methods of preparation, coating application techniques and their influence on the corrosion behavior of coatings is presented briefly. Newly developed strategies to enhance the protection efficiency of graphene-polymer matrix coatings are also covered concisely. The authors hope that this review will assist prospective academicians and researchers in developing novel highly efficient graphene-based anticorrosion composite coatings for industrial applications.
