Electrochemically oxidative copolymerizations of aniline (AN) and o-aminobenzene sulfonic acid (OSA) with mole ratio of 25/75 in the presence of carbon nanotubes (CNT) and acid-treated CNT (fCNT) on indium tin oxide electrode were conducted to investigate the electrocatalytic effects of the nanotubes on the copolymerizations. The P(25AN-co-75OSA)/CNT and P(25AN-co-75OSA)/fCNT composites were subsequently investigated into their electrocatalytic activities to the redox reactions of Fe(CN)63-/4- as a probe in aqueous solutions of different pH by cyclic voltammetry. The results revealed that CNT and fCNT both electrocatalyzed the oxidations during the copolymerizations of P(25AN-co-75OSA). The so-prepared composites exhibited electrocatalytic activity for the redox reactions of Fe(CN)63-/4- in solutions of up to pH 7.
