Abstract

In this work, different type of surface treatments on aluminium films have been performed. The changes that these treatments produce in the nature, composition, functionality, morphology and free surface energy on the aluminium surfaces will be analyzed. First treatment has been performed in two steps, the first one consists on activating the aluminium surface with sodium metoxyde in methanol and the time and treatment conditions on the nature of the formed surface will be studied. The second treatment has been performed in three steps, so between the activation step and the sylanization, an intermediate treatment has been done in order to try to insert a polymer by "in situ" polymerization on the aluminium surface. Those treated aluminium film surfaces have been characterized using infrared spectroscopy by Fourier transform (FTIR), contact angle measurement, surface energy determination and Dynamic Mechanic Thermal Analysis (DMTA).
