摘要
测定了聚氨酯－高氨酸及固态离子导体的交流阻抗谱，分析了离子导体的温度依赖性和低频介电特性．结果表明，聚氨酯－高氨酸锂固态离子导体具有较高的离子导电率，导电率的温度依赖性服从经验的ＶＴＦ方程，离子导体表现出非Ｄｅｂｙｅ型介电行为．
Based on the complex impedance spectra by means of alternating current measurement at low frequency (f<109), the solid dielectric charactericstic of Polyurethane-LiClO4 Electrolyte was analyzed. This sort of material showed non-Debye dielectric behaviour.
