高分子阴离子电导的研究

Study on the Conductivity of Polymer Anion

制备了含I-的固体电解质薄膜 ,用阻抗谱法测量了样品的I-电导率 ,分析了样品的频响特性曲线 ,用Wagner直流极化法测量了样品的电子电导。实验发现 ,此阴离子导体几乎和相应的含Na+有相同的离子电导率 ,且随着碘含量的增加 ,电导率增大。离子电导实验结果表明 ,在此阴离子导体中 ,电子电导占总电导率的 9% ,而空穴的电导率比电子电导率小 1～ 2个数量级。

Polymer films in epoxy resin -polyethylene glycal interpenetrating polymer networks containing iodine were prepared. The anion I - conductivity has been measured using impedence method. The electronic conductivity has been also measured according to Wagner method. The results showed that anion conductivity in this system were increased with increasing iodine content. This is a good anion conductors, but the electronic conductivity is rather higher, the electronic transition number t e is 9%,the hole conductivity is lower than two orders of electronic conductivity in magnitude.
