Supercapacitive behavior of graphene oxide/multiwalled carbon nanotube/polyaniline coating on graphite electrode

In the present study polyaniline (PANI) was chemically deposited on graphene oxidemultiwalled carbon nanotube (GrO-MWCNT) electrode. The capacitance of this composite film was investigated by cyclic voltammetry (CV). The capacitance of PANI/ GrO-MWCNT was reached to 401.69 mF.cm-2. This indicates that the improved electrochemical performance of PANI/ GrO-MWCNT is due to the enhanced electrical properties by PANI coating onto GrO-MWCNT.
