| 摘 要： | 利用交流阻抗法研究了靛红掺杂聚吡咯膜内的电荷传输，通过非线性最小二乘法拟合，得出了体系的等效电路，并计算出其电荷扩散系数和异相电子传递反应速率常数。实验结果表明，随着膜厚的增加，活性点增多，异相电子传递反应速率常数增大，同时表观扩散系数也增大。

| Abstract: | Charge transport in polypyrrole doped with indigo-carmine was investigated by the method of electrochemical alternating current impedance. By the nonllnear least square fitting, the equivalent circuit and parameter of each component are obtained- The apparent diffusion coefficients and heterogeneous electron transfer constants are given. It is found that, along with the increasing of film thickness, Dapp and ko increase also. |
