| Abstract: | A new multilayer film fabricated based on electrostatic attraction in this laboratory was firstly characterized by the electrochemical impedance spectroscopy. The relationship between the charge transfer resistance and double layer capacitance with the number of layers was obtained through analyzing the impedance data. It demonstrated that the multilayer film showed a unique structure with the film growth. Compared to other electrochemical methods, the electrochemical impedance spectroscopy was proved to be a very sensitive and useful technique for characterizing the multilayer films. |
