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 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.
