This is an ABSTRACT ONLYElectrochemical capacitive behaviour of the electropolymeric nickel tetra-aminophthalocyanine (poly-NiTAPc) supported on multiwalled carbon nanotube (MWCNT) platform is described. From the data in 1 M H2SO4, the MWCNT-poly-NiTAPc exhibited superior capacitance (112 mF cm2 or 777 F g1). The supercapacitance of the MWCNT-polyNiTAPc was found to be much better in 1 M H2SO4 than in 1 M NaOH medium. Impedance data proved that most of the stored energy of the MWCNT-poly-NiTAPc could be accessible at high frequency (1.6 kHz). The electrode is capable of undergoing continuous charge-discharge process for more than a 1000 cycles without any significant deterioration in the stability.enSupercapacitanceNickel tetraaminophthalocyanine electropolymerMWCNTsCyclic voltammetryGalvanostatic charge-dischargeArticleChidembo, A., & Ozoemena, K.
