Polystyrene (PS) spin coated thin films were modified by O2 and Ar plasma as
well as by UV irradiation treatments. The modified PS samples were compared with
plasma polymerized and commercial polystyrene. The effects of plasma (O2 and Ar) and
UV irradiation treatments on the surface and the bulk properties of the polymer layers were
discussed. The surface properties were evaluated by X-ray Photoelectron Spectroscopy and
Contact angle measurements and the bulk properties were investigated by FTIR and
dielectric relaxation spectroscopy. As a result only one second treatment time was sufficient
to modify the surface. However, this study was also dedicated to understand the effect
of plasma and plasma irradiation on the deposited layers of plasma polymers. The
dielectric measurements showed that the plasma deposited films were not thermally stable
and underwent an undesired post-plasma chemical oxidation.
