Wear-resistant and Robust Superamphiphobic Coating with Hierarchical TiO2/SiO2 Composite Particles and Inorganic Adhesives
In this study, superamphiphobic coatings, which could repel liquids with a surface tension as low as 21.6 mN/m (n-octane), were prepared using a spray-coating method based on flower-like hierarchical-structure and highly fluorinated TiO2/SiO2 Composite Particles. And the coating exhibited the broad liquid repellency to water-based composites, various oils, organic solvents and hot water. Moreover, the coating also possessed the remarkable mechanical and chemical stability in various forms of mechanical damage and harsh chemical environments. Multiple features, including antifouling, corrosion resistant, fuel transportation, gas adsorption, and protective coatings, etc.
