Paper Abstract

Multiple Specular Reflectance (MSR) infrared reflection-absorption spectroscopy has been applied to study surface modification by organosilane (sub)monomolecular layers. The spectrum of octadecyldimethylmethoxysilane immobilized on an oxidized aluminium substrate is compared to the absorption spectra of the monomer and the disiloxane condensation product. Formation of hydroxyl groups on a Si02 covered aluminium substrate by a UV-ozon treatment is shown. Simultaneously, organic contaminants are removed from the surface by the UV-ozon treatment. The chemisorption of 3-methacryloxypropyldimethylethoxysilane on UV-ozon treated Si02 has been examined at different surface coverages. An increase of the number of organosilane species at the surface is accompanied by a decrease of surface hydroxyl groups.
