초록

The surface and volume resistivity in the polymers, PE(polyethylene) and PP(polypropylene) mixtures are tested and measured by the ASTM D257(KS M3015) standard. Humidity effects on surface and volume resistivity in two polymers have been studied qualitatively at room temperature. The results of resistivity in these polymers show that the values of surface resistivity (and volume resistivity) at the humidity of 90% are remarkably small compared with those at the humidity of 50%, independing on applied voltage. When we varied the humidity in two polymers, it was found to takes many hours to recover into original surface resistivity (and volume resistivity) of these polymers.
