- Abstract
Polyvinylidene fluoride/graphene oxide (PVDF/GO) composite nanofibers were fabricated by electrospinning technology, to enhance the output performance of triboelectric nanogenerators (TENG) based on PVDF. These nanofibers were assembled into vertically contact-separate TENG to investigate the influence of GO mass fraction on the output performance of TENG. By utilizing the COMSOL software, the output performance of the TENG was simulated and analyzed, and the variations of electric potential and electric energy density at different electrode distances were observed. This study provides theoretical support for the working principle of TENG. Moreover, the morphology and structure of the PVDF/GO composite nanofibers were characterized using scanning electron microscopy, while the output performance of the TENG based on PVDF/GO composite nanofibers was characterized using a digital oscilloscope. The results indicate that the TENG based on PVDF/GO composite nanofibers exhibits excellent output efficiency when the GO mass fraction is 0.06%. The output voltage is approximately 350 V, and the short-circuit current is around 28 µA, and under impedance matching conditions, the maximum peak power is approximately 9.66 mW, with a power density of approximately 3.86 W/m². The TENG prepared by PVDF/GO composite nanofibers exhibits excellent output performance, capable of powering 120 LEDs, hereby demonstrating potential application prospects in the field of energy harvesting.
