| Popis: | Dielectric materials with high energy density at low electric fields play an important role in the development of electronic devices. In this study, flexible dielectric composite films are reported by semiconductor nanofibers as fillers and PVDF as matrix. Compared to pure PVDF, the polarization of the composite films was significantly improved at low electric field by the addition of a trace of BiFeO3 fibers. Based on the mixing rule, the effect of interface area on the polarization of composite films was discussed. The change of filler content was positively related to the interfacial area and polarization between filler and PDVF matrix in the composite films. The change of filler content also affected the content of α-phase and β-phase in composite films. |
