Polymer Surface Treatment by Atmospheric Pressure Low Temperature Surface Discharge Plasma: Its Characteristics and Comparison with Low Pressure Oxygen Plasma Treatment

摘要

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 (O_2) plasma treatment, is examined. As one compares the treatment by atmospheric pressure plasma to that by the low pressure O_2 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.
