The surface treatment of polystyrene and polyester using the DC Pseudo-glow Discharge is studied in this paper. The DC Pseudo-glow Discharge was systematically employed as a function of plasma device parameters under different operating conditions including different current (I) (15-50 mA), different time (t) (10-60 s), different distance (d) (1, 3 and 5 mm) between inter-electrodes, different mesh anode transparency (T) (19, 46 and 65%), distance between the polyester sample and the mesh anode (D) (2-12 mm) and different air pressure in plasma exposure system (P) (2-8 torr). The best optimization of these parameters were performed by the measurements and estimation of mechanical properties and water absorbency which were supported by the Infrared (IR) and Yellowness (color) tests.
