Origin of the effect of GO on TENG performance.

(a) Surface potential decay and (b) the normalized surface potential decay of PVDF/GO nanofibers with different concentrations of GO. (c) TEM images of PVDF nanofibers containing 0.7% GO. Schematic diagrams of PVDF/GO nanofibers showing the (d) distribution of GO on a nanofiber and (e) stored charge on the surface of a GO sheet.
