A New Approach for the Fabrication of Hydrophobic Silica Coatings on Glass Using Sol–Gel Method

Abstract

The aim of this study is the generation of hydrophobic silica coatings on glass substrates using tetraethoxysilane and phenyl triethoxysilane using sol-gel method. The surfaces were characterized for their water contact angles, SEM, AFM, and FT-IR techniques. The concentrations of the phenyl triethoxysilane were investigated and optimized to obtain the best hydrophobic coating.
