摘要：

Amorphous network polymer electrolytes were derived from poly(propylene oxide) (PPO) and phenyl isocyanate complexed with lithium perchlorate. Two ionic relaxation processes were found in the complex impedance spectra. Dynamic mechanical spectra showed two relaxation peaks in the high cross link density samples and T1-rho as a function of the temperature obtained by Li-7-NMR study has a well defined minimum. The peak position and the half width of D-LAM band obtained by FT-Raman spectra were found to depend on the salt concentration. These results strongly suggest the interaction of lithium cation and network chains.
