Abstract

The ac field (E_ac) amplitude dependence of dielectric response has been investigated for poly (vinylidene fluoride-trifluoroethylene- chlorofluoroethylene) relaxor terpolymer films. The frequency dependence of the temperature of the permittivity maximum T_m can be well described by the Vogel-Fulcher relation for Eac in the range from 1.33 to 80 MV/m. T _m remains nearly constant at an Eac level lower than 13.3 MV/m, and starts decreasing with Eac increases further. The two parameters fitting to the Vogel-Fulcher relation, freezing temperature T_f and activation energy E_a, vary little for Eac below 26.7 MV/m and then T_f decreases, while E_a increases for higher Eac level.
