Abstract:
1. A thin layer comprising a first layer including two or more materials selected from the group consisting of one or more organic materials and one or more inorganic materials wherein the thin layer has a composition gradient in the thickness direction and is produced by a sol-gel process, wherein the first layer includes tetraethylorthosilicate (“TEOS”), 3-glycidyloxypropyltrimethoxysilane (“GLYMO”), γ-aminopropyltriethoxysilane “γ-APS”) and dimethyldimethoxysilane (“DMDS”) in a molar ratio of about 2:2:1:1; further comprising a second layer formed on the first layer wherein the second layer includes two or more inorganic materials, having a composition gradient in the thickness direction, and has a small difference in surface energy at the interface with the first layer, wherein the two or more inorganic materials of the second layer are selected from the group consisting of metal oxides, metal nitrides and silicon oxides, and the composition of the second layer changes continuously in the thickness direction.
