Abstract

There have been investigated charge states and dielectric properties of polyethylene –based compositions with low-molecular additions PE+PbCrO4 and PE+Cr. New region of depolarization initiates to be manifested by electrets from polarized films. It is shown that observed effect is related to the repeated electron capture into deeper traps at the expense of internal local electric field. It is also established that the change of dielectric constant (ε), dielectric loss tangent (tgδ) and specific resistance (ρv) is associated with the change of supra molecular structure of polymer matrix, structure and thickness of boundary layer and the change of interphase interactions of composition components depending on polarization condition..
