Physicomathematical analysis of surface modification of polymers by glow discharge in SF6+N2 medium

In this paper, surface modification of dielectric polymers, having different physical and chemical properties (polyimide—PI, polystyrene—PS, Polyethylene terephthalate—PET), treated in contourized glow discharge in SF6+N2 gas medium near cathode was studied. The electret state, formed as a result of modification, caused an increase in the surface energy. Surface charge densities and contact angles of dielectric polymers whose surfaces were activated under identical conditions, were measured.
