Abstract
Herein, we report a two-step electrospinning and potentiostatic electrodeposition method to fabricate electrodes with graphene/polypyrrole-coated carbon nanofiber core-shell architecture for supercapacitor applications. The electrospun carbon nanofiber core acts as an electrically conductive substrate that enables the incorporation of the graphene/polypyrrole shell. Constructing a porous and interconnected one-dimensional configuration with a carbon nanofiber core facilitates the maxim
