摘要：

Comparative studies of the relationship between ion pair/cluster formation and PEO complexation for different salt concentrations and temperatures have been made up to 100-degrees-C for the system M(CF3SO3)2PEO(n), where M = Ni, Zn and Pb, and n = 3-24 The nu (COC) modes for PEO and the nu (SO3) modes for CF3SO3- have been observed by FTIR spectroscopy. For M = Pb, a large fraction of the PEO is complexed at all concentrations, with free CF3SO3- occurring together with ion pairs/clusters. The ion pair/cluster formation is enhanced by increasing salt concentration and temperature. In the Ni and Zn systems, non-complexed PEO is favoured at low salt concentrations and ion pairs/clusters dominate at all concentrations.
