The D ‐ E (electric displacement vs. field) hysteresis curve of a ferroelectric polymer is conventionally measured by the Sawyer–Tower method. The effect of the electrical conductance of the polymer on the measured hysteresis curve is theoretically analyzed and a new method is proposed for elimination of the error arising from the conductance. Examples of original and corrected hysteresis curves of vinylidene fluoride–trifluoroethylene copolymer are presented.
