用碳酸丙烯脂（PC）、高氯醚锂（LiClO4）与聚丙烯腈纤维（PAN）复合，制备出较高电导率的离子复合膜（18×10－3S／cm，26℃）。用电化学交流阻抗谱对其进行了测试，分析了离子导电率的温度依赖性，并用非线性最小二乘拟合程序对其进行了模拟，得到了其等效电路，从而对此体系微相离子传递与转移进行探讨。
The composite membrane with higher conductivity (18 × 10-3 S / cm, 26 ℃) was prepared by the compounding of propylene carbonate (PC), LiClO4 and polyacrylonitrile fiber (PAN). The electrochemical impedance spectroscopy was used to test the temperature dependence of ionic conductivity. The nonlinear least square fitting procedure was used to simulate the temperature dependence of the ion conductivity. The equivalent circuit was obtained, Ion transfer and transfer to explore.
