Abstract: The electret state of nanocomposites based on low density polyethylene has been investigated. It was found that the increase of montmorillonite content in the samples leads to an increase in the absolute values of thermally stimulated currents. The treatment of samples in a corona discharge leads to an increase in the effective surface charge density. In the positive and negative corona discharges, the LDPE samples acquire approximately the same charge, and their modification with montmorillonite slightly increases the amount of charge. A relationship has been established between the initial value and the relaxation rate of the technological charge of the electret. The higher the technological charge, the faster its decline occurred.

Key words: polyethylene, nanocomposite, electret, technological charge, charge relaxation.
