Preparation of Superhydrophobic P-TiO₂-SiO₂/HDTMS Self-Cleaning Coatings with UV-Aging Resistance by Acid Precipitation Method.

ABSTRACT: The superhydrophobic coatings for outdoor use need to be exposed to sunlight for a long time; therefore, their UV-aging resistances are crucial in practical applications. In this study, the primary product of titanium dioxide (P-TiO₂) was used as the raw material. Nano-silica (SiO₂) was coated onto the surface of P-TiO₂ by the acid precipitation method to prepare P-TiO₂-SiO₂ composite particles. Then, they were modified and sprayed simply to obtain a superhydrophobic P-TiO₂-SiO₂/HDTMS coating. The results indicated that amorphous nano-SiO₂ was coated on the P-TiO₂ surface, forming a micro-nano binary structure, which was the essential structure to form superhydrophobic coatings.
