Preparation of Electrode Material for Supercapacitor based on Electropolymerized Poly (ortho-Methoxyaniline)/MWCNT Composite Film

In this work, ortho-Methoxyaniline (OMA) was electropolymerized onto multi-walled carbon nanotubes (MWCNTs) modified glassy carbon electrode (GCE) in 0.5 M H2SO4 solution. Theelectrochemical response of the POMA/MWCNT film was higher than pure POMA. The galvanostatic charge-discharge and electrochemical impedance spectroscopy experiments showed that the POMA/MWCNT composites possess good capacitive characteristics. Stability of the nanocomposite was also investigated.
