Abstract
The temperature dependence of the dielectric permittivity has been determined on poly(vinylidene fluoride-triflouroethylene) copolymer films for both virgin and preliminary polarized states. It was found that the polarization process led to considerable changes in the dielectric response of the copolymer. A change in the dielectric permittivity, the shift of the maximum of temperature dependence and an almost unchanged relaxor-like behavior were observed.
