摘要： 为了获得电导率高的快离子导体,人们主要从晶格结构考虑,这在寻找银和铜的快离子导体工作中取得很大成功。然而在探索实用价值更大的碱金属离子导体时,却遇到了困难。此后,人们又把注意力转向聚合物。Fenton等人[1]首先报导了由碱金属盐和聚环氧乙烷(简称PEO)组成的络合物,其后Armard等人[2]研究了PEO-NaSCN的电学性能.Liang[3.4]首先把γ-Al2O3微粒分散在离子导体LiI中,所得的固态混合物比纯LiI高约两个数量级。Weston[5]等人在研究α-Al2O3对PEO-LiClO4影响时,认为α-Al2O3的加入虽然增加了该离子导体的机械稳定性,但离子电导率却降低了。本文在研究PEO-NaSCN离子导体电学性能的基础上[6],进一步探讨了不同含量的第二相γAl2O3对PEO-NaSCN电导率的影响。

Abstract: The PEO-NaSCNis used as a matrix and the γ-Al2O3 is taken as dispered second phase particles (Dspp). The conductivity in PEO-NaSCNis increased by the addition of Dspp and When the y-Al2O3 and the PEO-NaSCNis in the ratio of 30 to 100, the maximun appears. The conductivity of PEO-NaSCNis five times of magnitude higher than that of the PEO-NaSCNat room temperature. Then with the increasement of the(γ-Al2O3) content the conductivity of it decreases rapidly.
