| 摘 要： | 利用交流阻抗谱仪，FT－IR，DSC研究了聚氨酯／盐体系的离子状态和电导率，通过自由体积理论推导了聚合物固体电解质电导率的计算公式，为使公式更符合实际离子的存在状态，用变温红外光谱首次对离子状态随温度的变化进行跟踪研究，对公式进行了改进，并从电导率数据计算出了VTF公式应用于聚氨酯／LiCF3SO4体系的各种参数，讨论了盐浓度对参数的影响。

| Abstract: | The solid stat electrolyte of poly(ethylene oxide)-urethane/salt complex was investigated by means of AC impedance, FT-IR, DSC and ionic conductivity equation was deducted using free volume theory. For the practicality of the equation, the ionic state in the samples was analyzed by FT-IR and the free volume equation by the free ionic concentration in poly(ethylene oxide)-urethane/salt complex was rectified. Using numerical fits for conductivity data in the whole temperature range, the parameters of the VTF equation in PEU/LiCF 3SO 3 were got. |
