A topical review on hybrid quasi-ceramic coatings for corrosion protection

Abstract

AbstractA set of unique properties can be derived by a proper combination of organic and inorganic segments in a coating composition. The synthesis of such hybrid coatings is a challenging task due to that a number of variable parameters need to be optimized to achieve the desired results. Similar to the copolymerization of macromolecular segments in a common solvent, sol–gel chemistry could provide a viable alternate for the development of single-phase coating composition. The coating derived through sol–gel and wet chemistry displays homogenous physical and chemical characteristics. A large variety of chemical moieties containing labile functional groups are available for the development of new coating compositions. This article briefly reviews such studies that are reported in majority of the academic sector.
