Applications of graphene in organic anticorrosive coatings

Abstract

The problem of corrosion of materials has lasted for a long time, corrosion causes damage to the structure of buildings and bringing loss of economy. The coating method, which is an easy and economical way to solve the problem, is still unable to satisfy the needs limited by the paints properties. However, this can be solved by introducing graphene, by its special 2-D material properties, to the paint. And a lot of researchers are working on this now. This paper mainly focuses on the overview of how graphene be applied to anti-corrosive coatings, the problems that are faced, what are solutions for those, and what are the advantages that graphene has in the area. Resulting that graphene is mainly used with organic anti-corrosion materials, by filling the holes in those materials to stop the corrosion molecules from infiltrating through. Graphene can also be used as containers, carrying corrosion inhibitors that would be released and fill the crack when the coating is damaged. By modifying graphene, problems like agglomeration and accelerating corrosion can be solved. The result will be used for researchers who are looking for a conclusion in the graphene anti-corrosive coatings research area and provide the main focuses and details.
