A Study on Conduction Characteristics of Oriented Polypropylene Film
초록
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.
