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.
