Abstract

Thin polyethersulfone (PES) films were irradiated with boron ions at doses between 1013-1016B+/cm2 and energies of 50, 130 and 180 keV. The induced changes of structural and optical properties were studied in detail. The influence on sensoric properties (moisture uptake, conductivity) was also in the focus of interest. The results of vibrational spectroscopy and X-ray photoelectron spectroscopy (XPS) indicate that in dependence on dose and energy of implanted boron ions the sulfone bonds are destroyed, and carbon-rich, amorphous and graphite-like structures are formed. This structural changes cause an increase of the conductivity of the surface films to a value of 10−8 Ω−1 at a dose of 1016 B+/cm2 from an as- prepared value of 10−15 Ω −1 and an increase of the saturation concentration during the moisture uptake.
