Abstract: Pre-orientation stretching of high-density polyethylene improves the charge stability of electrets produced in corona discharge. Electrets made of oriented polyethylene charged in the corona under uniaxial tensile mechanical stress have even greater stability. The increased stability of electrets is due to the capture of electrons in deep structural traps formed after the rupture of macromolecules during orientation and mechanical stress. By the method of thermally stimulated electron emission, it is shown that the charge of electrets is formed at the expense of electrons. New convenient formulas for calculation of electrical voltages in multilayer insulation with electrets were obtained.
