Atmospheric plasma do not require the need of vacuum equipments, and are inexpensive in capital investment as well as in operation cost. The main challenge of this study is to develop a powerful non-equilibrium cold atmospheric discharge for chemical applications with high efficiency and high selectivity. 　　Arc discharge plasma treatments of polymer for surface modifications have been studied using contact angle measurement, atomic force microscopy(AFM)，X-ray photoelectron spectroscopy （XPS）and adhesive test. The arc discharge plasma is found to modify the PC、PMMA and PP surface in both the morphology and the composition. The contact angle is reduced dramatically for these three polymer substrates. AFM measurements show that changes in surface morphology appear to increase with extending processing time. Oxidation reaction results in oxidized polar groups on the processed polymer surface. These oxygen-containing groups contribute significantly to the increase of surface wettability and film adhesion.
