Organosilanes such as (3-mercaptopropyl)trimethoxysilane (3MPT) are used to promote a variety of desirable interfacial properties such as chemical durability, alkali resistance, electrical conduction, insulation, surface protection and adhesion. The results presented here demonstrate that Raman spectroscopy is a useful technique for evaluating molecular monolayers of organosilanes adsorbed onto metal surfaces. The data indicate that (3-mercaptopropyl)trimethoxysilane (3MPT) forms a self-assembled monolayer on silver surfaces. Upon hydrolysis, the molecules undergo a reorientation to form a Si-O-Si network across the silver surface. The Si-O-Si network contains a variety of Si-OH defects, which are similar to other silica sol-gel systems. 29 refs., 5 figs.
