Surface Morphology of Silica Films Derived by the Sol-Gel Method and Its Application to a Water Repellent Glass

Surface Morphology of Silica Films Derived by the Sol-Gel Method and Its Application to a Water Repellent Glass

Silica films with various surface morphologies, such as flatness, mesoporosity, uneveness, convexity, were prepared by hydrolysis and polymerization of tetraethoxysilane, Si(OC2H5)4(TEOS) and methyltrietoxysilane, CH3Si(OC2H5)3(MTES) under acid-catalyzed conditions. The morphology of coatings could...

Zusammenfassung:Silica films with various surface morphologies, such as flatness, mesoporosity, uneveness, convexity, were prepared by hydrolysis and polymerization of tetraethoxysilane, Si(OC2H5)4(TEOS) and methyltrietoxysilane, CH3Si(OC2H5)3(MTES) under acid-catalyzed conditions. The morphology of coatings could be changed by changing the molar ratio (denoted as f, f=KITES/TEOS) in TEOS-MTES mixture, as well as the conditions of drying process and heat treatment temperature. Especially, in the case of 5
