【摘要】 测定了聚氨酯离聚物固体电解质的交流阻抗谱，分析了离子导体电导率的温度依赖性和低频介电特性。结果表明，聚氨酯离聚物固体电解质具有较高的离子电导率，电导率的温度依赖性不服从Ａｒｒｈｅｎｉｕｓ型方程，而服从经验的ＶＴＦ方程。离子导体表现出非Ｄｅｂｙｅ型介电行为，具有与无机固体电解质相似的低频介电特性。更多还原

【Abstract】 The low frequency dielectric behavior of polyurethane anionomer electrolyte which is characterized by single ion conductive mechanism are analyzed by the complex impedance data.Experimental results show that polyurethane ionomer has higher ionicconductivity.The temperature dependence of conductivity does not follow Arrhenius equation,but the result can be interpreted by using the Voyel-Tamman-Fulcher(VTF) equation.The dielectric response of this material is similar to that of inorganic superionic conducters and departs from the Debye behavior.更多还原
