Abstract:
1. A graded mixed metal Zr:Si sol-gel, comprising: (a) a first layer made by mixing in a suitable carrier an effective amount of an organozirconium with tetraethyl orthosilicate (TEOS) to form a sol-gel network; (b) a second layer made by mixing in a suitable carrier an effective amount of the organozirconium and an organosilane selected from the group consisting of: 3-aminopropyltriethoxysilane, 3-glycidoxypropyltrimethoxysilane, p-aminophenyltrimethoxysilane, m-aminophenyltrimethoxysilane, allyltritnethoxysilane, n-(2-aminoethyl)-3-aminopropyltrimeethoxysilane, 3-arninopropyltrimethoxysilane, 3-glycidoxypropyldiisopropylethoxysilane, (3-glycidoxypropyl)methyldiethoxysilane 3-glycidoxypropyltrimethoxysilane-, 3-mercaptopropyltrimethoxysilane, 3-mercaptopropyltriethoxysilane, 3-methacryloxypropylmethyldiethoxysilane, 3-methacryloxypropylmethyldimethoxysilane, 3-methacryloxypropyltrimethoxysilane, n-phenylaminopropyltrimethoxysilane, vinylmethyldiethoxysilane, vinyltriethoxysilane, vinyltrimethoxysilane, and mixtures thereof to form a sol-gel network, and (c) an organometallic alkoxide having Ti or Al in at least one of the first layer and the second layer; and wherein the first layer has a stronger ceramic character than the second layer.
