Polystyrene thin films were modified by the radio frequency argon plasma treatment. Effect of plasma processing on surface morphology was investigated by scanning electron microscopy and an atomic force microscopy. Volume structure of polystyrene films has been revealed after surface treatment by radio frequency argon plasma and was represented polymer coils organized in chains 1.8 μm in length and 0.21 μm in width. Dependence of surface roughness and wettability on plasma exposure time was investigated. It was shown that varying of treatment time in the small range leads to considerable changing of the surface roughness parameter and to formation of nano-sized pores.
