Augmented triboelectric properties of graphene-filled poly(vinylidene difluoride- co -hexafluoropropylene) (PVDF-HFP) nanofibers

. The improved performance of the electrospun graphene/PVDF-HFP nanofibrous TENGs could be attributed to increased interface polarization and enhanced charge transfer, indicating more effective seize and storage of triboelectric electrons. Furthermore, the fabricated TENGs remained stable when tested for over 20 000 cycles and were capable of powering an array of 1000 light-emitting diode bulbs. The electrospun graphene-filled nanofibrous TENGs demonstrated significant potential for collecting mechanical energy and supplying power to electronic devices.
