Notes:
The thickness of the adsorbed layer of two glass finishes, vinyl tris (2-methoxyethoxy) silane and gamma-aminopropyltriethoxysilane, was measured by ellipsometry. The vinyl silane was adsorbed on glass from solutions in water and in methyl ethyl ketone. The adsorption from water resulted in a film initially at least 50 Å thick, which increased in thickness with time. Adsorption from methyl ethyl ketone solution resulted in a film of about 10 Å. The amino silane was adsorbed on glass and on chrome from soutions in water. Adsorption on glass resulted in a film at least 60 Å in thickness, which remained constant over a period of about 5 hours. Adsorption on chrome resulted in a film about 10 Å in thickness. From the results it appears that a polymer, rather that small molecules of glass finish, is adsorbed from the water solution on glass and that small unpolymerized “finish” molecules are adsorbed from the methyl ethyl ketone solution.
