Title: Energy-Effective Plasma-Chemical Surface Modification of Polymers and Polymeric Materials at Atmospheric Pressure
Keywords: corona discharge, oxygen-containing plasma, plasma surface modifi-cation, surface density of active power
Abstract: The plasma-chemical surface modification performed at atmospheric pressure through corona or barrier air discharges is characterized by a specific change in the surface density of the active electric power. Two characteristic regions of changes in the surface density are observed: the first one, up to 25 W/m2, is the energy- and technology-effective region of the oxygen-containing technological plasma, and the second one, above 100 W/m2, the energy- and technology-ineffective region of plasma containing mostly nitrogen oxides. Based on experimental investigations of the plasma-chemical modification of high-porous non-woven textile on the basis of polyethylene terephthalate, it is proposed to use the surface density of active power as a basic parameter of the technological process. Using that parameter permits defining the energy- and technology-effective region of this process.
