Preparation and properties of TiO2 superhydrophobic filter media modified by silane coupling agent KH570

TiO2 sol was prepared by sol-gel method using tetrabutyl titanate as precursor and acetic acid as catalyst, and then hydrophobically modified TiO2 sol was obtained by reducing its surface energy with γ-methacryloxypropyl trimethoxysilane (KH570), the modified TiO2 sol was sprayed on the surface of t...
