Flexible piezoelectric nanogenerator based on [P(VDF-HFP)]/ PANI-ZnS electrospun nanofibers for electrical energy harvesting

Abstract Over the past decade, piezoelectric nanogenerator have attracted much attention to harvest mechanical energy from abundant resources in nature. Here, ZnS microspheres is prepared by hydrothermal method and core-shell structured PANI/ZnS are synthesized situ polymerization then used as filler for preparation of flexible [P(VDF-HFP)] based nanogenerator. The P(VDF-HFP)/PANI-ZnS Electrospinning technique. composite improves content electroactive phase significantly interfacial polarization between particles polymer matrix. Among all samples, [P(VDF-HFP)]/2 wt% PANI-ZnS nanofibers exhibited high peak-to-peak output voltage 3 V compared with neat (~ 120 mV). In addition, dielectric constant observed nanofibers. These results implies that fabricated efficient can be utilized harvesting system.
