摘要：
Segmented polyether urethane (SEU) and urethaneurea (SEUU) were synthesized using ABA type triblock copolymer as a prepolymer, where A stands for poly(oxyethylene) and B stands for poly(oxytetramethylene). Lithium perchlorate was dissolved in SEU or SEUU to prepare LiC104 complexes (SEU/LiC104 and SEUU/LiC104) in film form. The highest conductivities observed here were 5.13x10-6 S cm-1 at 30°C and 3.34x10-5 S cm-1 at 50°C for LiC104/SEUU (oxyethylene-units content, 31 mol%). The ionic conductivity of these complexes was found to show the Arrhenius type temperature dependency. The effect of lithium perchlorate dissolution on the morphology of SEU and SEUU were also discussed. © 1990 Springer-Verlag.
