The bonding of the ester groups with the oxide surfaces was found to be not stable in the presence of water and also not in the presence of a compound capable of chemisorption with the aluminum oxide surface.
ESTER FUNCTIONAL GROUP FREE
The two compounds showed differences in the free to bonded ν(C O) infrared peak shift, indicating differences in bonding strength with the oxide surface between the two types of molecules. However, the oxides showed differences in the amount of molecules bonded to the oxide surface, and a clear relation was observed with the hydroxyl concentration present on the oxide surface, which was determined from XPS measurements. For all oxides, the ester groups showed the same ν(C O) carbonyl stretching vibration after adsorption, indicating very similar bonding occurs. The ester groups were found to show hydrogen bonding with hydroxyls on the oxide surfaces through their carbonyl oxygens. The extent by which these bonded ester molecules resisted disbondment in water or substitution by molecules capable of chemisorption was also investigated. The purpose of the investigation was to find out what type of ester−oxide bond is formed and whether this is influenced by changes in the composition and chemistry of the oxide. The different oxide layers were made by giving typical surface treatments to the aluminum substrate. The bonding of two types of ester group-containing molecules with a set of different oxide layers on aluminum has been investigated using infrared reflection absorption spectroscopy.
