ROLL-TO-ROLL ATMOSPHERIC PRESSURE PLASMA TREATMENT OF POLYAMIDE FOILS

Popis výsledku v původním jazyce

The subject of this contribution is a hydrophilic ambient air plasma treatment of polyamide (PA) foils using diffuse coplanar surface barrier discharge with a concavely curved configuration of electrode system. The short plasma exposure time in the range of 0.5–2 s was sufficient for hydrophilization of foils. It was carried out also the comparison of discharge input power (400 W, 600 W) influence on water contact angle (WCA) values. A significant effect of plasma treatment on PA foils hydrophilicity increasement was observed even after 0.5 s of treatment at the input power of 400 W when WCA was reduced from value 65° to 40°. The most significant wettability increase of PA surface was achieved after plasma treatment at a higher input power of 600 W. In this case, WCA decreased from value 65° to 28° after 2 s of plasma treatment. Even one month after the treatment the WCA values did not reach the initial values before treatment. No morphological changes were observed on the surface of PA foils after the plasma treatment.
