Electrode effects and electrical conduction in polyimide Kapton HN films

In this work steady-state conduction currents in two-side metallized polyimide (PI) Kapton HN samples, as well the one-side metallized samples subjected to positive and negative corona were measured at temperatures ranging from 490 K to room temperature and in fields from 2 to 120 MV/m. Also experiments were carried out upon thermally stimulated currents and space charge distribution in samples after charging.
