Sol-Gel Coatings: Durable, Versatile Surface Treatments for Modern Applications

Sol-gel coatings are thin films or layers which are applied as a liquid and later solidify into a solid gel on a substrate surface through solvent-based reactions. The sol-gel process involves transitioning solutions of molecular precursors ("sol") into networks of both inorganic and organic polymers ("gel") on the substrate surface. The synthesis of sol-gel coatings involves hydrolysis and polycondensation reactions of molecular precursors such as metal alkoxides or metal salts. Compared to conventional coating methods, sol-gel processing offers better control over the coating's composition, homogeneity, and microstructure due to its solution-based and relatively low-temperature synthesis.
