Influences of thickness and electrode materials on electrical conduction in polyethylene films

In this paper, influences of some factors on the electrical conduction in high-density polyethylene (HDPE) films are studied. HDPE samples with different thickness have been prepared. Their differences in DC electrical conduction are reported and discussed. It's found that the samples with different thickness have different DC conduction properties, the current density increases and then decreases with the increase of the thickness of samples. On the other hand, in the current density measurements, electrodes made of different metal materials including copper, aluminum, and steel have been used. The influences of different metal electrodes on DC conduction in HDPE films are discussed.
