摘要: The complexes of polyurethane containing double bonds with LiClO4 were formed, and cross-linked films produced by UV radiation. All the uniform, transparent, flexible smooth-faced a considerable mechanical strength. ionic conductivities several series polymers different molecule weights PEG segment measured, which highest is 8.09×10-5 Scm-1 at 300 K under anhydrous atmosphere. Also conductivity deeply influenced weight soft content LiClO4. transport number Li+ about 0.57. Structure characteristic measurement such as DSC, XRD, IR etc., have been done conductive mechanism discussed.
