Summary: In this study, the performance outputs of triboelectric nanogenerators (TENGs) were enhanced using polyvinylidene fluoride (PVDF)/fullerene (C-60) composite nanofibers (NFs). It was found that the incorporation of C-60 into the PVDF matrix improved the output power of the TENG devices, but an excessive amount of C-60 resulted in a decrease in power. The increase in C-60 content in the PVDF matrix enhanced the TENG performance by improving trap charge ability and electronegativity, and the output power was sufficient to operate a display device.
