资源简介：
The evaluation of electrocaloric properties of a material can be achieved by two methods: either by the indirect method which uses Maxwell relations to link the electrocaloric effect to the polarization versus temperature or by the direct measurement of the heat flux response to an electric field variation. In this paper we show how the heat flux method is able to evaluate the efficiency of different types of electric field cycles applied to a ferroelectric material with hysteresis. We present experiments on the polymer P(VDF-TrFE)
70/30 and discuss how to improve the cooling power in connection with respect to the non zero electrical conductivity of the material.
