Summary The poling of biaxially stretched poly(vinylidene fluoride) (PVDF) films which have been metallized on both sides results at the poling temperature of 115 °C and the poling field of 400 MV/m in almost complete conformational change from T-G-T-¯G to the trans conformation as well as in a residual polarization of at least 11×10−2 C/m2. The transition temperature Tf of the field-induced conformation transformation in the crystalline regions is found to be Tf = 75 °C. The thermally stimulated decrease of polarization proceeds gradually and is not characterized by a defined Curie point.
