These surfaces can differ markedly with regard to their chemical compositions and topographical structures. Characterizations of these surfaces after exposures to three organosilanes, gamma -GPS, BTSE and gamma -APS, indicate that the amount of silane adsorbed in each case shows a tendency to increase both with the number of OH groups detected at the oxidized aluminum and with the surface roughness. The XPS data are consistent with the adhesion of gamma -APS occurring through H bonding, especially via NH3+ groups.}, keywords = {ADHESION, DURABILITY, GROWTH, INTERFACES, OXIDATION, OXIDE, photoelectron, THIN-FILMS, XPS}, isbn = {0218-625X}, url = {://000168218600007}, author = {Kono, M. and Sun, X. and Li, R. and Wong, K.

The thicknesses of these layers were estimated to be about 10 and 4 Angstrom respectively. The interpretations were guided by difference spectra, especially for the Zr system, and it was concluded that different interactions operate at these two PET-metal interfaces. For the amounts deposited, Zr bonds especially to O atoms in PET, whereas Al beads to both C and O atoms; the latter metal shows both tending to carbonyl groups and direct Al-C bonding to the benzene-like rings. Comparisons were made for the behaviors of these systems on exposure to oxygen, and they were compared further with related systems.}, keywords = {CHEMISTRY, EVAPORATED ALUMINUM, OXIDE, photoelectron, POLY(ETHYLENE-TEREPHTHALATE), POLYETHYLENETEREPHTHALATE, POLYVINYL-ALCOHOL POLYMER, SPECTROSCOPY}, isbn = {0218-625X}, url = {://000088415700018}, author = {Wong, P.
