The oil wettability and sliding property of polymethylsilsesquioxane (PMSQ) based organic inorganic hybrid coating films prepared from methyltriethoxysilane and various metal alkoxide were investigated. The wettability of oil increased in the order of PMSQ<Ta-<Ti-<Al-PMSQ, and was strongly affected by the surface roughness. The friction coefficient showed that Ti-PMSQ among hybrid coating films was the lowest value, which was found to be due to the presence and maintenance of the lubricating oil film during the sliding tests.
