Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF) has been widely used in a variety of fields due to its superior piezoelectric properties. PVDF’s piezoelectric performance is affected by the presence of polar phase in the crystalline structure. The electrospinning process was used in this study to achieve high ? phase ratios in the PVDF crystalline structure using various additives (graphene, boron nitride, and quartz (SiO2)). The Taguchi experimental design method was used to determine the most significant parameters affecting ? phase content from seven factors, as well as the optimal levels of the significant factors. The Fourier transform infrared, x-ray diffraction, scanning electron microscopy, energy-dispersive x-ray and differential scanning calorimetry analyses were used to characterize the composite PVDF nanofiber mats produced under optimal conditions, and the output voltage was measured using an oscilloscope. The composite PVDF nanofiber mat with the highest ? phase concentration demonstrated a maximum output voltage of 8.68 V under optimal conditions, indicating that it outperformed than pure PVDF under equal electrospinning conditions. © 2022 IOP Publishing Ltd.eninfo:eu-repo/semantics/closedAccessdesign of experimentelectrospinningenergy harvestingPVDF nanofiber? crystal phaseAdditivesDesignDifferential scanning calorimetryEnergy harvestingFluorine compoundsIII-V semiconductorsNanofibersPiezoelectricityScanning electron microscopySilicaCrystal phasisCrystalline structureNanofiber matsOptimal conditionsOutput voltagesP.V.D.FPhase's contentsPiezoelectricPVDF nanofiber? crystal phaseElectrospinningArticle10.1088/1361-665X/ac8f782-s2.0-85138981213
