Abstract: | A poly(ethylene oxide) urethane and a model compound of hard segment(HD) were prepared in this study. Solid polymer electrolytes were got from the blends of polyurethane, HD and NaClO 4. The samples were characterized by mean of FT IR and AFM. Effects of salt concentration on ion polymer interaction and further on morphologic structure of the composites were investigated and some interesting results were obtained. The results show that HD and concentration of NaClO 4 have an important effect on ion polymer interaction and morphologic structure of the complex. It is also found that in AFM pictures of the samples there is a transition point and ion polymer interaction of the polyurethane/salt systems play an extremely important role on morphologic structure. |
