Electrochemical synthesis of poly(2,6-pyridinediamine)(PPa) in aqueous sodium hydroxide solution has been carried out by using cyclic voltammetry for the first time.The scanning electron microscopy(SEM) revealed the interpenetrating network structure of the as-prepared PPa film,which makes it possible that anions can be doped into the polymer in the oxidation process, and vice versa in the reduction process.The results from FT-IR spectrum provided a possible polymerization mechanism of 2,6- pyridinediamine.
