Thermally Stimulated Depolarization (TSD) measurements with a superimposed piezoelectric noise allowed us to identify the ferroelectric-to-paraelectric phase transition in vinylidene fluoride/trifluoroethylene (VDF/TrFE) copolymers, with different molar ratios. A second peak was also detected in TSD measurements which maintain the ferroelectric features of the material. Long relaxation processes always accompanied both peaks. Using the initial rise method we calculated the activation energies for these relaxations. We found 0.73 eV for the ferroelectric-to-paraelectric peak transition and 0.33 eV for the other. Two peaks were also observed in the 90/10 mol % VDF/TrFE copolymer. However it is considered, hitherto as having a non ferroelectri...
