多嵌段聚醚氨酯脲为基质的新型高分子固态离子导体

Polymer Solid Ionic Conductor Based on Segmented Polyether Polyurethaneureas

本文合成了一系列聚乙二醇型多嵌段聚醚氨酯脲,而且用这类聚醚氨酯脲与高氯酸锂制得了一种新型的高分子固态离子导体复合物,在室温和50℃之间,其电导率比聚环氧乙烷为基质的固体电解质的高一到二个数量级,它还具有优良的综合性能。因此,对于室温薄膜蓄电池来说,这种新型的固体电解质是一类良好的候选材料。

A setes of poly(ethylene glycol)-type segmented polyether poly(urethanc ureas) (PEUU) was synthesized, and the polymer solid ionic conductors were then prepared by complexing of PEUU and LiClO_4. The conductivities of such solid ionic conductor are 1-2 orders of mash/rued higher than those of poly (ethplene oxide)-based solid electrolytes. Besides, the former has better overall properties. Thus this new polyether poly(urethane ureas) electrolyte has potentialuse as room-temperature thin-film battery.
