| Abstract: | The character and structure changes of polypyrrole (PPy) in the process of electrochemical oxidation-reduction was studied using cyclic voltammetry and in situ FTIR spectroscopy. The result shows that the polymerized PPy film electrode is of thin layer electrode model in the process of electrochemical oxidation-reduction. One of every 12 pyrrole units in the polypyrrole is involved in the reaction. It was found that the IR absorption of C=C,C-N and N-H bonds in PPy structure increased as the electropotential jumped positively. The molecular structure may trun towards quinoid mode. |
