Abstract: Protective hybrid coatings prepared by sol-gel method is an environmental- friendly and sustainable surface treatment technique. The coating derived from the hydrolysis and condensation reaction of precursors can dramatically improve the over-all properties of the substrate. This article summarizes the mechanism and advantages of the technique and discussed its research progress and application in stainless steel, aluminum alloy, carbon steel, PMMA,PC,meanwhile, describes the future development of the hybrid coatings. concrete and wood.
