Cold plasma treatments of polymers, dry processes, allow either the elaboration of hydrophilic or hydrophobic surfaces. For example, a poly(propylene) film treated in nitrogen plasma shows a surface having a hydrophilic and basic character since amino groups are attached onto the surface during the treatment. The treatment induces an increase of the surface tension of the polymeric material, which may be sometimes destroyed by an aging effect. For the treatment of poly(propylene) in nitrogen plasma, the aging is mostly due to a motion of attached groups from the surface to the bulk of the material and some oxidation of radicals formed during plasma treatment. The surface radicals formed and used for a post‐reaction such as grafting are characterized in terms of chemical nature, density and reactivity.
