چکیده
Flexible piezoelectric nanogenerators (PENGs) are gaining attention as sustainable power sources for wearable and self-powered electronic systems due to their capability to convert mechanical energy into electrical output. The present work aims to enhance the performance of a flexible PENG by incorporating aluminum nitride (AlN) nanoparticles into a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) matrix. The nanocomposite fibers were fabricated through electrospinning technique with an. The structural, morphological, and compositional features were examined using Fourier Transform Infrared Spectroscopy (FT-IR), Energy Dispersive X-ray Spectrometry (EDX), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD). FT-IR and XRD analyses confirmed the presence and enhancement of the electroactive β-phase in the composite, while FE-SEM images indicated uniform fiber formation with well-distributed nanoparticles. The optimized device with AlN loading of 15 wt% achieved an output voltage of 2.64 V and a current of 0.49 μA, showing over a tenfold enhancement in voltage and an order of magnitude increase in current compared with pristine PVDF-HFP fibers. The nanogenerator also delivered a power density of 12.00 mW/m² under a 20 MΩ load. These results confirm that AlN nanoparticle incorporation effectively improves dipole alignment and stress transfer, positioning the PVDF-HFP/AlN composite as a strong candidate for high-performance piezoelectric energy harvesting applications.
