This field must be compensated anyhow in order to obtain stable residual polarization. It is shown that in corona poled PVDF this compensation is performed by injected and deeply trapped charges. Experimental evidence for the charge trapping has been obtained from the dynamics of apparent conductivity during poling. Irreversible decrease in the conductivity has been observed during the buildup of ferroelectric polarization independently on poling conditions. Appropriate calculations have shown that compensating charges are trapped not at the boundaries of crystallites, as usually believed, but in transition zones separating polarized parts of the volume from non-polarized ones.enpolymersconductivityseparatinganyhowArticle
