摘要: 固态离子导体作为一种高能密度电池中的电解质在传感器中的实际应用受到了普遍关注[1-3]。聚氧化乙烯与碱金属盐的复合物是其中研究得最早、最多的一类。但它在室温下电导率较低、力学性能不理想,人们正着力于研制综合性能优良的高分子固态离子导体。

Abstract: The poly(ethylene glycol) polyurethaneureas (PEUU) and the complexes composed of thePEUU and LiClO4 were examined by means of XPS and DSC. The DSC studies indicatethat the soft segment's Tg of the complexes increases with increasing LiClO4 concentration;it shows that LiClO4 dissolves selectively in the poly (ethylene glycol) (PEG) phase. TheXPS data show that the soft segment of PEG is significantly richer on the surface. Beingadded to PEUU, LiClO4 is advantageous to the further enrichment of PEG on the surface.It is also an evidence of selective dissolvation of LiClO4 in the PEG phase.
