Description/Abstract

Mesoporous manganese dioxide supercapcitor electrode materials were electrochemically deposited onto silicon substrates coated with Pt using triblock copolymer species (Pluronic P123 and F127) as the structure-directing agents. Deposited electrodes of manganese dioxide film were physically characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and were electrochemically characterized by cyclic voltammetry (CV) in 0.5M Na2SO4 electrolyte. Maximum specific capacitance (SC) values of 449Fg?1 was obtained at a scan rate of 10mVs?1 from F127 templated mesoporous MnO2.
