Abstract

We report the preparation of hybrid organic-inorganic films deposited by dip-coating from a base-catalyzed sol containing tetraethoxysilane and 3-methacryloxypropyltrimethoxysilane as the silicon source, and ethyl-2,4,6-trimethylbenzoylphenylphosphinate as the photoinitiator. The films were cured with a UV lamp, obtaining a change in refractive index upon UV irradiation through the formation of an interpenetrated silica-methacrylate network. The refractive index increased of Δn = 14 × 10^-3 after UV treatment. The synthesis is simple and reproducible and yields films with optical quality which can be useful as materials for applications in optics and information storage.
