ABSTRACT
Approaches involving a variety of organic and inorganic precursors have started yielding huge results for a promising, safe and effective coating system. The most widely applied formulations for hybrid phase of high-performance anti-corrosive coatings are silica-based materials such as (epoxy, acrylic and polyurethane)-silica. These coating materials are currently being utilized as frameworks for incorporating nanomaterials. This facilitates the fabrication of nanocomposite coatings with lots of advantageous properties. Therefore, by combining the compatible organic and inorganic counterparts, the properties of coating materials could be improved to augment the desirable functionalities. This follows the fact that inorganic nanomaterials have not only offered great resistance to electrochemical corrosion via barrier mechanism but also serve as nanocontainers for hosting corrosion inhibitors for smart release and self-healing. The organic materials on the other hand are an extensive group of nitrogen-based compounds that show good interaction with metals through adsorption via the lone pair of heteroatoms such as N, O and S. Therefore, this chapter presents extensive research knowledge in the area of organic–inorganic hybrid nanocomposite coatings for corrosion protection of metals.
