摘要：
Two-layer film corona-electrets based on low-density polyethylene and copolymers of ethylene with vinyl acetate of various brands were studied. The dependence of the electret characteristics of two-layer corona-electrets on the percentage content of polar groups in the copolymer constituting the bottom layer was analyzed. Data on thermally stimulated depolarization and thermally stimulated relaxation of the surface potential served as a basis for suggesting a mechanism of depolarization of two-layer corona-electrets.
