Kinetic Features of Modification of Polycarbonate in Oxygen Plasma

Changes in the composition of the surface layer of Lexan 8010 polycarbonate after treatment in plasma of the positive column of oxygen glow discharge have been investigated. The effect of the amount of the processed polymer on the etching kinetics and surface modification of polycarbonate has been shown. It has been established that an increase in the amount of the polymer processed in plasma leads to a change in the gas phase composition, the concentrations of active species, and their fluxes onto the sample, and, as a consequence, a change in the composition of the modified surface layer of polycarbonate.
