Supercapacitive behaviour of a novel functional material, nickel (11) octa [(3,5-biscarboxylate)-phenoxyl phthalocyanine (NiOBCPPc) upon covalent integration with phenylamine functionalized single-walled carbon nanotubes (SWCNT-phenylamine) is reported for the first time. The supercapacitive behaviour of the hybrid (NiOBCPPc-SWCNT-phenylamine) was investigated using galvanostatic charge-discharge and electrochemical impedance spectroscopy. Using a more reliable galvanostatic charge-discharge method, the NiOBCPPc-SWCNT-phenylamine hybrid exhibited superior geometrical capacitance (similar to 186 mF cm(-2)) compared to either NiOBCPPc (similar to 54mF cm(-2)) or SWCNT-phenylamine (similar to 74mF cm(-2)) at a current density of 138 mu A cm(-2). The NiOBCPPc-SWCNT-phenylamine gave excellent stability of over 1000 charge-discharge continuous cycling. (C) 2010 Elsevier B.V. All rights reserved.
