Dependence of the PVDF ferroelectric polarization on the electric field obtained by two methods

We show that the dependence of ferroelectric polarization on the electric field in PVDF can be determined either using the constant current or a modified Sawyer-Tower technique. Measurements with and without polarization switching were performed and prior to each one the sample was short-circuited for several hours. The results compare very well and the small difference was attributed to the existence of a delayed polarization which is not accounted for in the calculation.
