Abstract
The polymer treatment with a low-temperature plasma jet generated on the atmospheric pressure surface discharge (SD) plasma is performed. The change of the surface property over time, in comparison with low pressure oxygen (O2) plasma treatment, is examined. As one compares the treatment by atmospheric pressure plasma to that by the low pressure O2 plasma of PS (polystyrene) the treatment effects were almost in complete agreement. However, when the atmospheric pressure plasma was used for PP(polypropylene), it produced remarkable hydrophilic effects.
