DC arc plasmas containing He and Ar, which were made to rotate by the application of a magnetic field, were used for generating vacuum UV light (VUV) to modify polymer surfaces. Polymers such as poly(tetrafluoroethylene) (PTFE), fluorinated ethylene propylene copolymer (FEP), polyimide (PI), UPDLEX-S and UPILEX-R were modified with and without optical filters for different exposure times. PTFE was also exposed to helium and argon arc plasmas at different exposure temperatures. After the treatment, the polymerfilms were measured by weight loss, contact angle and Scanning Electron Microscopy (SEM). Copper was sputter deposited onto some of the treated samples and the adhesion between copper and polymer film was measured using a peel test.
