Abstract

The dc bias dependence of dielectric properties has been investigated for poly (vinylindene fluoride-trifluoroethylene-chlorofluoroethylene) relaxor terpolymer films. The frequency dependence of the temperature of the permittivity maximum, T_m, was analyzed using the Vogel-Fulcher (VF) relation. Two threshold fields, ∼30 and 160 MV/m were found in the electric-field dependence of T_m. T_m shows a minimum at ∼30 MV/m and a maximum at ∼160 MV/m. The VF parameters activation energy E_a and freezing temperature T_f respectively show a maximum and a minimum at ∼25 MV/m.
