INTERACTION OF EPOXY MODEL MOLECULES WITH ALUMINUM, ANODIZED TITANIUMAND COPPER SURFACES - AN XPS STUDY

The interaction of a variety of epoxy model molecules (representative of uncured, part-cured and fully-cured epoxy/polyamine adhesive/coatin g systems) with aluminium, anodised titanium and copper was examined u sing XPS. No interaction with epoxy functionalised molecules could be observed, but a strong interaction with nitrogenous molecules was note d. Copper surfaces were found to form copper-molecular complex films, whereas anodised titanium and aluminium appear to form adsorbed monola yers. However, the binding mechanism of these molecules on titanium an d aluminium showed significant differences, with Bronsted (protonic) a cid/base bonding more important on titanium than aluminium.
