Structure and Adsorption Characteristics of Silane Coupling Agents on Silica and E-glass Fiber; Dependence on pH

Abstract

Fourier transform infrared spectroscopy was used to study the adsorption of silane coupling agents on silica and E-glass fiber surfaces. The structures of the adsorbed species of gamma-aminopropyltriethoxysilane (gamma- APS) coupling agent under various preparation conditions are postulated on an interpretation of the NH deformation and SiOH stretching modes. The amount of gamma-APS deposited on high-surface-area silica depends on the pH of the treating solution. On the contrary, the amounts of adsorption of gamma- methacryloxypropyltrimethoxysilane (gamma-MPS) and vinyltriethoxysilane (VS) coupling agents are independent of ph.
