DYNAMIC MECHANICAL PROPERTIES OF POLYMER SOLID IONIC CONDUCTORS BASED ON SEGMENTED POLYETHER POLYURETHANEUREAS
多嵌段聚醚氨酯脲类固态离子导体的动态力学性能

Dynamic mechanical properties of the poly(ethylene glycol)polyurethaneurea(PEUU)and the polymer complexes formed by PEUU and LiClO_4 were studied.The influenceof adding LiClO_4 to PEUU on the mechanical relaxation and the activation energy were dis-cussed.The master curves of frequency-temperature dependence of the storage elastic modulusfor PEUU-LiClO_4 complexes with different salt concentration were carried out by the WLFequation using the glass transition temperature at certain frequency as a referencetemperature.The reason that results in broadening of the distribution of the relaxation times wasalso interpreted.
