Paper Abstract

The wetting property of polymers is very important in different applications such as optics, biomaterials, textiles, aerospace, and thin film adhesion. Hence the strong interest in developing new technology for modifying this property at will. Low energy ion beams can induce this modification in the first surface atomic layers. Nitrogen ions of 500 eV/at. and argon ions of 3 keV/at. under partial pressure of oxygen were used to bombard the surface of polycarbonate samples to a fluence of 5 X 1016 at/cm2 and 2.1 X 1017 at./cm2, respectively. After implantation, the samples were stored in two different environments over controlled intervals of time. Characterization of samples was performed by means of XPS, ERD ExB and RBS. The result show an increase of the oxygen concentration near the surface for all implanted samples. Also, desorption of hydrogen was observed after implantation of argon under a partial pressure of oxygen. These results confirm the formation of new functional groups such as C-OH for all treatments. These groups are known to enhance the wettability of the polycarbonate surface.
