Polymer Bulletin Aims and scope Submit manuscript

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.
