STUDY ON PREPARATION OF UV CROSS-LINKING FILMS OF POLYURETHANE-LiClO4 COMPLEXES AND THEIR IONIC CONDUCTIVITY 下载免费PDF全文
The complexes of polyurethane containing double bonds with LiClO4 were formed, and cross-linked films were produced by UV radiation, All of the films were uniform, transparent, flexible and smooth-faced with a considerable mechanical strength. The ionic conductivities of the films of several series of polymers with different molecule weights of PEG segment were measured, of which the highest is 8.09×10-5S·cm-1 at 300K under anhydrous atmosphere. Also the conductivity is deeply influenced by the molecule weight of the soft segment PEG of the polyurethane and the content of LiClO4. The transport number of Li+ is about 0.57. Structure characteristic measurement much as DSC, XRD, IR etc., have been done and the conductive mechanism is discussed. 相似文献
