Abstract

In this study, superamphiphobic coatings, which could repel liquids with a surface tension as low as 21.6 mN m−1 (n-octane), were prepared using a spray-coating method based on a flower-like hierarchical structure and highly fluorinated TiO2/SiO2 composite particles. And the coating exhibited broad liquid repellency to water-based composites, various oils, organic solvents and hot water. Moreover, the coating also possessed remarkable mechanical and chemical stability towards various forms of mechanical damage and in harsh chemical environments. Multiple features enable the coating to find more vital applications in antifouling, corrosion resistant, fuel transportation, gas adsorption, and protective coatings, etc.
