Hydrophilization of porous polyethylene films by cold plasma of different types

Porous PE films have been modified using high-frequency discharge plasma (in air) and dielectric surface barrier discharge plasma in static (in oxygen and nitrogen) and dynamic (in argon) regime. A noticeable increase in the hydrophilicity of samples and their adhesion to coatings has been established. Changes in chemical composition and morphology of the surface resulting from plasma treatment and subsequent aging have been studied. The treatment regime have been established under which sufficient hydrophilicity is reached and mechanical strength is preserved.
