Abstract
The impulse corona discharge was applied to modify surface of polypropylene films. The modified surface was analyzed by contact angle measurements and ESCA. The results were compared to those treated with AC corona discharge. The impulse corona treatment provided a similar contact angle and a similar[O]/[C] ratio on the polymer surface to those in AC corona treatment. On the other hand, [N]/[C] in impulse discharge was much lower than that in AC pulse discharge. The total power input in the impulse corona discharge, however, was lower than that in AC corona discharge to achieve a similar level of surface modification. It was also observed that the lower repetition frequency, the lower contact angle, and the higher[O]/[C].
