摘要： 关于高分子量聚环氧乙烷(PEO)与碱金属硫氰酸盐络合物电导方面的工作先后报道的有Wright、Tanzella、Lee及王超英等.本工作研究PEO中EO链节与NaCNS或KCNS的摩尔比及添加γ-丁内酯对导电率的影响以及其结晶结构与导电率的关系,得到某些尚未见报道的结果。

Abstract: Ionic conductivity behavior of complexes obtained from high molecular weight polyoxy-ethylene (PEO) and NaCNS or KCNS has been studied.The results showed that the comp-lexes at EO/metal ratio > 4 exhibited a knee in the Arrhenius plot of conductivity vs tem-perature. At EO/NaCNS = 20, conductivity at 25℃ approached 2.8 ×10-6Ω-1cm-1, which ishigher than those at EO/NaCNS = 4 or 50. For complexes of PEO with KCNS the condue-tivity at 25℃ reached 2 ×10-5Ω-1cm-1 at EO/KCNS = 20, while at EO/KCNS = 4 the condu-ctivity obeyed the Arrhenius equation at the temperature ranging from 20 to 90 ℃. Addi-tion of γ-butyrolactone evidently increases the conductivity of the complex.
