Recently there have been considerable interests in nanometerial study. In this work, we have used carbon nanotubes (CNTs) and polypyrrole (PPy) conducting polymers (CPs) as models to make a nanotube and conducting polymer composite material. Under electro-oxidation condition, the PPy/CNT films can be grown on conventional substrates such as a glassy carbon electrode in aqueous and non-aqueous media. These nano-conjugated materials are based on the doping of CNTs particles into conducting polymer network while oxidatively polymerizing. CNTs serve as dopants and solely supporting electrolytes in the preparation. The CP/CNT new composite materials have showed promise not only in a potential environmental remedy such as conversion of highly toxic Cr(VI) into less harmful Cr(III), but also in electrocatalysis of the quinone/hydroquinone redox reaction. Voltammetry, bulk electrolysis with coulometry, AC impedance, and EQCM techniques have been used to elucidate the preparation, ion transport, and intermolecular interaction processes within these composites.
