本文为提高聚苯醚磺酸锂(SPPOLi)的导电性能, 将聚乙二醇(PEG)与之共混,DSC分析发现SPPOLi的玻璃化转变温度随PEG的加入有所下降, 并且对于高磺化度的样品下降更为明显; X射线衍射表明, PEG可降低SPPOLi凝聚结构的有序程度;发现通过共混, 电导率有了较大提高, 并且仍保持了单离子的传导性。

In this paper, SPPOLi was blended with PEG. The results of DSC analysis demonstrated a decrease of Tg for SPPOLi with adding of PEG, moreover, the higher the sulfonation contents, the more evident the decrease of Tg. WAXD showed that PEG could deteriorate the condense state structure for SPPOLi. The conductivity was improved by mixing PEG with SPPOLi, and the blends maintained the single-ion conducting property.
