Aromatic polyimide films were subjected to RF-oxygen plasma and pulsed electrical discharges in distilled water treatment for 2, 4, and 6 minutes. The film surface was investigated by means of Fourier Transform Infrared Spectroscopy, Atomic Force Microscopy, and contact angle measurements. It was observed that the polymer film surface became more hydrophilic after the RF-oxygen plasma exposure due to the formation of the oxygen-containing polar groups, while the sample surface became more hydrophobic after the water plasma treatment due to the surface segregation of the CF3 groups.
