交替马来酸酐共聚物多缩乙二醇酯盐络合物的离子传导性（Ⅱ）

IONIC CONDUCTION OF POLYMER ELECTROLYTES BASED ON A ALTERNATING MALEIC ANHYDRIDE COPOLYMER WITH OLIGO-OXYETHLENE SIDE CHAINS(Ⅱ)

深入研究了交替马来酸酐共聚物多缩乙二醇酯（ＢＭ３５０）－ＬｉＣＦ２ＳＯ３两种碱金属盐络合物的离子传导性能。实验结果表明，室温电导率最大可达５．０８×１０^（－５）Ｓ·ｃｍ^（－１）。络合物的玻璃化转变温度随盐含量的增加而上升。电导率随盐浓度的变化而出现一极大值。电导率均随温度升高而增加。络合物的导电行为符合ＶＴＦ方程。高弹态中分子链热运动是离子传输的动力。

In this paper a study of the BM350-LiCF_3SO_3 complexes is presented.A series of AC impedance measurements in the frequency range 10 kHz～10 MHz and in the temperautre range 25～100℃is reported.These solid polymer electrofyte films showed ionic conductivities of the order of 10￣(-5)S .cm￣(-1) at room temperature.The ionic conductivity of these complexes was studied as a function of temperature and salt concentration.At high salt concentratioris,the more pronounced fall in conductivity in the solid medium has been interpreted as being due to effect of Tg and bulk viscosity on ion transport.Conductivites which displayed non-Arrhenius behavior were analysed the VogelTammann-Fulcher equation and interpreted on the basis of the configurational entropy model derived by Gibbs and coworkers.
