High surface area conducting polymers with nanoscale dimensions are an important aim for device applications. Here is reported the polymerization and electrochemical oxidation of aniline at multiwalled carbon nanotube electrodes. Polyaniline films formed on these nanotube whiskers are oxidized more easily and produce a higher current density during the anodic oxidation compared to conventional electrodes such as those made from Pt. Scanning electron microscopy images indicate that the morphology of the films is granular, consisting of nanosized domains.
