N2 - In order to improve the qualities of polycarbonate based materials used in different industries we deposited transparent films, obtained from controlled ratios of mixtures between hexamethyldisiloxane with nitrogen and hexamethyldisilazane with nitrogen and/or hydrogen, on polycarbonate substrates using a capacitively-coupled radio-frequency discharge. Varying the discharge parameters and the gas mixtures rates we constructed multifunctional layered coatings. In order to determine the properties and functionality of the obtained coatings, we choose to analyze the layered structures by depth sensing indentation method, contact angle measurements, surface energy calculation and SEM (scanning electron microscopy) for determining the mechanical properties (like hardness, fracture toughness, adhesion, internal stress, abrasion resistance); and by ellipsometry and photospectroscopy for the optical properties (like thickness, color, refractive index). Also plasma diagnostic was performed by means of optical emission spectroscopy (OES). The films behavior covers a wide range of material properties from polymer-like to inorganic coatings. The multilayered polymer coatings obtained are hard, transparent and have a high resistance to outdoor weathering and UV exposure. Therefore are suitable for covering for example the headlights in the automobile industry or house windows.
