Abstract

In order to investigate the conduction characteistics of the biaxially oriented polypropylene film, several measurements have been carried out in the range of temperature between 5['c] and 25['c] as well as the field intensity between 10[MV/m] and 300[MV/m]. The whole range of the characteristics observed at 15['c] appears to be divided into five regions` the Ohmic conduction region due to ionic carrier below 40[MV/m], the region from 40[MV/m] to 70[MV/m] in which the conduction mechanism is attributed to Poole-Frenkel effect, the region from 70[MV/m] to 82[MV/m] in which the negative resistance characteristics are observed, then the region from 82[MV/m] which is dominated by Schottky effect and finally, the region from 240[MV/m] up to the point where dielectric breakdown occurs in which the mechanism is based on Flowler-Nordheim theory.
