Piezoelectric properties of zinc oxide/iron oxide filled polyvinylidene fluoride nanocomposite fibers

Abstract Piezoelectric nanogenerators (PENG) with flexible and simple design have pronounced significance in fabricating sustainable devices for self-powering electronics. This study demonstrates the fabrication of electrospun nanocomposite fibers from polyvinylidene fluoride (PVDF) filled zinc oxide (ZnO)/iron (FeO) nanomaterials. The fiber based PENG shows piezoelectric output voltage 5.9 V when 3 wt% ZnO/FeO hybrid nanomaterial is introduced, which 29.5 times higher than neat PVDF. No apparent decline observed almost 2000 s attributed to outstanding durability. performance correlated ?-phase transformation studies Fourier infrared spectroscopy crystallinity differential scanning calorimetry. Both these show respective enhancement 3.79 2.16% values PVDF-ZnO/FeO composite. Higher dielectric constant value obtained same composite (three PVDF) confirms increased energy storage efficiency as well. Thus proposed soft a promising mechanical harvester, its good properties reveals ability use this material power sources wearable electronic devices.
