One-step potentiostatic electrodeposition of polypyrrole/graphene oxide/ multi-walled carbon nanotubes ternary nanocomposite for supercapacitor

A ternary nanocomposite consisting of polypyrrole (PPy), graphene oxide (GO) and multi-walled carbon nanotube (MWCNT) for supercapacitor was prepared via facile one step potentiostatic technique. Field emission scanning electron microscopy (FESEM) images displayed a randomly entangled nanostructure...
