Corrosion is the process through which a metal deteriorates as a result of chemical reactions with its surroundings. Corrosion inhibitors are a highly efficient method of preventing corrosion on metal surfaces. New studies are focusing on how to make coatings more effective toward corrosion. One cutting-edge method involves chemically bonding the surfaces of modified fillers in order to increase the better dispersion of coating used and the surface of the material on which coating is applied. In this regard, the surfaces of the filler are activated and modified by grafting a variety of functional groups in order to make them active. Surfaces with coating material matrices that include modified compounds as fillers improved their adherence to metal and increased the various properties like thermal, anticorrosion, etc. of the various coating materials, which used to shield metals from corrosive environments. This was accomplished by improving the adhesion of the modified compounds to the metallic surfaces. Therefore, in this article anti-corrosion coatings are first described in detail, including their synthesis, characterization, and structure-property-performance relationship.
