ABSTRACT
Plasma contains highly activated species such as electrons, ions, and radicals. Such activated species can interact with the surface of polymeric materials to modify the surface. In chemistry, the modification may be radical reactions rather than ionic. Therefore, we believe that the surface modification by plasma treatment is a combination of hydrogen abstraction from the polymer surface and recombination between a carbon radical in the polymer surface and a radical in the plasma. If we can isolate radicals from the plasma and interact predominantly with the polymer surface, modification will proceed faster and effectively.
