Fig. 4: Electric and dielectric properties of neat P(VDF-TrFe) and its composites determined experimentally.

a Electric current as a function of applied voltage for the different samples. b Electric conductivity values for each sample. The specific conductivity values are given within the graphic, where the error bars representing the standard deviation. c Real part of the dielectric response and d tanδ as a function of frequency for P(VDF-TrFE)-based composites with different filler types and content.
