폴리프로필렌 필름의 전도현상

Conduction Phenomena of the Polypropylene Film

The conducting currents of polypropylene film was measured a function with electric fields at temperature of 25,35,45( C). It appears that there are four regions of conducting currents, depending upon the strength of the applied electric field` ohmic region based on ionic conduction, Poole-Frenkel region, Schottky region and negative resistance region. Several information of dielectric constant and potential barrier height were obtained.
