| Summary: | The article investigates how the polarization temperature in the corona discharge field and preannealing modes of polyvinylidene fluoride copolymer films with tetrafluoroethylene effect thermally stimulated depolarization currents. The parameters of electrically active defects responsible for relaxation processes, the amount of charge (Q) released during depolarization and the value of the piezoelectric module d33 were determined for samples with different polarization temperatures. The article discusses the best temperature conditions for creating a piezoelectric state in polyvinylidene fluoride films.
