Metal-polymer interface in M-I-M structures involving aluminum and polyethylene terephthalate films: study by the thermally stimulated current method

In this paper, we investigate the influence exercised by heat-treatments on the charge exchange properties of the aluminum-polyethylene terephthalate (PET) interface by means of the Thermally Stimulated Depolarization Currents (TSDC) method. Thermomechanical Analysis (TMA) and X-ray Photoelectron Spectroscopy (XPS) measurements support the TSDC results and give an insight in the nature of the physical changes occurring at the interfaces.
