Dynamics of Coupling Agents on Metal Oxides Surfaces
Abstract
The focus of the present work is on the microscopic dynamics of interfacial molecules, specifically silane coupling agents on metal oxide surfaces. The deposition of alkoxy silane coupling agents on a metal oxide surface is a two step process. The alkoxy groups are hydrolyzed and the silanols then bond with surface hydroxyls through condensation reactions. The effects of hydrolysis conditions, coupling agent concentration in solution, and the metal oxide surface on deuterated silane coupling agent motion and structure were probed. For the conditions used here, the chemical composition of the solid substrate does not have a strong effect. The spectra do not exhibit a great difference in molecular motion between coupling agents deposited on the silica and γ-aluminasurfaces.
