Figure 8. (A) Udis and (B) η of different regions of the 0-2-0 sample tested with different electric fields. (C) Radar plots of pure polyvinylidene difluoride (PVDF), 2 wt% monolayer 0.55Bi0.5Na0.5TiO3-0.45(Sr0.7Bi0.2)TiO3 (BNT-BST)/PVDF and trilayer 0-2-0 sample. (D) Overdamped discharge curves. (E) Time dependence of Wd with different electric fields of the 0-2-0 sample. (F) Variation rule of Wd with time for pure PVDF and the 0-2-0 sample at 400 kV/mm.
