Abstract :
Some study results point out that the shift path of detrapped charges in cellular polymer due to the electret field is along the solid dielectric layer near the boundary of the cavities from the detrapping position (Behrendt, 2006). In this paper, the influence of formation of macroscopy dipoles and their density on dielectric properties, charge storage and shift behaviour of detrapped charges was discussed.
