Abstract

A method for quantitative analysis of 3-aminopropyltriethoxysilane (γ-APS) and N-(N-vinylbenzyl-2-aminoethyl)-3-aminopropyltrimethoxy-silane hydrochloride (cationic vinylbenzyl silane, CVBS) on muscovite mica powder has been developed with the use of diffuse reflectance FT-IR spectroscopy. The adsorption isotherms determined by this method are reported. The results are compared with a previous study of the adsorption of aminosilanes by ESCA, and possible models of the adsorbed layer are discussed.
