Electrical conduction in polyethylene with semiconductive electrodes

The electrical conduction characteristics of polyethylene with semiconductive electrodes have been investigated at electric fields of 10 to 600 kV/cm and at temperatures of 25 to 100/spl deg/C. It was found that the conduction characteristics of the polyethylene were influenced not only by the constituents of the polyethylene but also the electrode materials. Space-charge-limited conduction was found to be the major conduction mechanism in all cases. Differences between conduction characteristics depending on the constituents of the XLPE are described and their causes are discussed.<
