Solid poly(ethylene oxide)–urethane electrolytes were prepared from blends of polyurethane and NaClO 4 . The samples were characterized by FTIR, DSC, atomic force microscopy, and complex impedance analysis. The effect of the concentration of NaClO 4 on the poly(ethylene oxide)–urethane/NaClO 4 complex were studied. The results showed that the concentration of NaClO 4 had an important effect on the ion–polymer interaction, ion–ion interaction, glass‐transition temperature, morphologic structure, and ionic conductivity of the complex. We also prepared a model compound of hard segments and found that the conductivity of the complex decreased when the model compound was blended into the complex. © 2001 John Wiley & Sons, Inc.
