Effect of barrier discharge on stability of electret state of high-density polyethylene

Resumo

The electret state of high-density polyethylene subjected to an electric gas barrier of an AC discharge is studied. It is established that under the effect of the discharge a negative charge is formed on the film surface. Using thermally stimulated polarization, we study the space-charge processes in both the thermoand corono-electrets processed in the barrier discharge in the air gap between the dielectrics (glass–polyethylene). A comparison of the stability of the electret state in polyethylene films is carried out.
