Abstract
Preparation and evaluation of organic－inorganic polymer hybrid coatings were investigated. The coatings were prepared by the hydrolysis of methyl-trimethoxysilane (MTMOS) with poly (N-vinylpyrrolidone) (PVP) and subsequent condensation. The hybrid coatings exhibited odd-shaped surface by the measurement of surface roughness and microscope observation. As a result, the contact angle against water on the coatings increased and the sliding angle decreased. ATR－FTIR and XPS spectroscopy indicated that PVP was incorporated into the siloxane structure including methyl groups near the surface. Therefore, the siloxane structure was disturbed and the hybrid coatings exhibited odd-shaped surface.
