Electrochemical behaviour of poly-o-toluidine films in a wide range of pH

This work deals with the study of the electrochemical behaviour of poly-o-toluidine (poT) films in a wide range of pHs. Polyaniline (pAni) films were first reported to become passive ca. pH 5. However, using microelectrodes and buffer solutions these film were shown to be electroactive up to ca. pH...
