Figure 5From: Vertically aligned ZnO nanorod core-polypyrrole conducting polymer sheath and nanotube arrays for electrochemical supercapacitor energy storageElectropolymerization process of the polypyrrole growth over ZnO nanorods. (A) Electrochemical polymerization of Py monomer and ClO4 conjugation. (B) Model of electropolymerization growth of PPy sheath over ZnO nanorods in the presence of SDS surfactant and (C) homogenous growth of PPy sheath over ZnO nanorods after a number of pulsed current cycles.Back to article page
