Description The surface of polyamide-12 (PA12), polypropylene (PP) and polyethylene (PE) foils was modified in order to improve their surface properties by two types of atmospheric pressure plasma sources - diffuse coplanar surface barrier discharge (DCSBD) and industrial corona discharge. A significant increase in wettability after plasma treatment was observed for all polymers. AFM measurement showed that the surface morphological changes due to plasma treatment strongly depend on the polymeric material. PE surface was significantly affected by plasma in comparison with PP and PA-12 surface.
