Figure 6From: Vertically aligned ZnO nanorod core-polypyrrole conducting polymer sheath and nanotube arrays for electrochemical supercapacitor energy storageCyclic voltammetric plots of the electrode with nanostructured ZnO nanorod core-PPy sheath. PPy nanotube after etching away ZnO nanorods for 2 and 4 h measured at scan rates (A) 5 mV.s-1 and (B) 10 mV.s-1.Back to article page
