Contribution of chemical interactions between AI atoms and different types of functional groups to the adhesion of Al-polymer systems

The adhesion of metal layers deposited onto polymer surfaces is determined by the concentration and bond strength of chemical and physical interactions between the metal atoms and the functional (polar) groups at the polymer surfaces. Each type of functional group makes a specific contribution depending on its concentration to the interfacial adhesion and consequentially to the shear or peel strength of metal-polymer systemes (cf., Fig. 1).
