“…On the other hand, the semi crystalline structure in the PVDF causes a different relaxation spectrum, when compared with the other thermoplastic polymers 14, 15. The relaxation behavior of PVDF has been investigated by various techniques 2, 8, 9, 16–18. Different methods have been used for the investigation of mechanical and dielectric relaxation of PVDF (e.g., for the mechanical relaxation, dynamical mechanical measurements (torsion pendulum), stress‐relaxation measurements, calorimetric measurements (DSC), and thermal expansion measurements; for dielectric relaxation, thermo‐stimulated depolarization current measurements (TSD), thermo‐stimulated current spectroscopy (TSC), capacitance measurements (three terminal capacitance bridge), and dielectric measurements (DEA)) 2, 6, 8, 16–23.…”
