Khalifa, M.Anandhan, S.2026-02-052019ACS Applied Nano Materials, 2019, 2, 11, pp. 7328-7339https://doi.org/10.1021/acsanm.9b01812https://idr.nitk.ac.in/handle/123456789/24286Herein, a facile approach was used to synthesize an ultrasensitive, durable, and flexible electrospun poly(vinylidene fluoride) (PVDF)/polyaniline (PANI)/graphitic carbon nitride nanosheets (g-C<inf>3</inf>N<inf>4</inf>) blend nanocomposite fibers (PPBF) based piezoelectric nanogenerator. PANI/g-C<inf>3</inf>N<inf>4</inf> nanocomposite (PGNC) was prepared prior to its dispersal in PVDF. This unpretentious synthesis approach exploited the ?-nucleating activity of g-C<inf>3</inf>N<inf>4</inf> along with the enhancement of electrical conductivity due to a network of PANI within individual PVDF nanofibers. Addition of PGNC and electrospinning synergistically enhanced the ?-phase content (?97%) of PVDF. The PPBF nanogenerator displayed remarkable improvement in the voltage and current output compared to pristine PVDF nanofibers (?1300%). The nanogenerator generated a voltage output of ?30 V and current output of 3.7 ?A with high stability and reproducibility (>50※000 cycles). The PPBF nanogenerator exhibited high-power density and conversion efficiency and was able to light up 70 commercial LEDs. The newly developed high performance nanogenerator could be a potential material in smart, self-powered wearable devices. © 2019 American Chemical Society.Carbon nitrideCrystallographyElectrospinningEnergy conversionFluorine compoundsNanocompositesNanofibersNanosheetsNitridesPiezoelectricityPolyanilineTextile blendsElectrical conductivityGraphitic carbon nitridesNanogeneratorPiezoelectric energy conversionsPiezoelectric nanogeneratorPoly (vinylidene fluoride)(PVDF)Poly(vinylidene fluoride)Self-poweredNanogenerators
