Abstract
Poly(ethylene terepthalate) films and fabrics were modified by low-pressure argon plasma at different area of samples been treated. Contact angles for water and glycerol were measured and surface energy was calculated for film surface characterization. Height of water capillary rise was measured for fabric. The changes in chemical structure of surface layer were analyzed by ATR-FTIR method. Influence of sample area on non-homogeneity of plasma modification was shown. Some experiments were performed with polypropylene treatment in flowing plasma afterglow to confirm the reactions of oxygen active species originated from gas products of poly(ethylene terepthalate) etching in argon plasma.
