Abstract
The interactions that occur between propyltrimethoxysilane (PTMS) and aluminum and iron oxide surfaces during the oscillatory absorption cycle were studied. The surface chemistry throughout the adsorption isotherm was characterized by using secondary ion mass spectrometry (SIMS). Results from this study support the hypothesis that the two distinct surface species involved in the oscillatory adsorption of PTMS onto metal oxide surfaces are the monomer and condensed phases of PTMS. Furthermore, the structure of the silane/metal interface at the peak of the oscillation was found to consist primarily of adsorbed PTMS monomers whereas at the asymptotic maximum it consists mainly of condensed PTMS molecules.
