Abstract
Polyvinylidene fluoride (PVDF) films and copolymer films of vinylidene fluoride and trifluoroethylene P(VDF-TrFE) have great potential applications in uncooled infrared detection due to their good pyroelectricities and ferroelectricities. It is important to investigate the mechanism of their electrical transport. In our present work, we found the differential conductivities of P(VDF-TrFE) films exhibit a sharp peak near the coercive field. And it is proposed that the peak is caused by the delocalization of polarons during the polarization inversion.
