Abstract


The purpose of this is to prepare with a lower content of crystalline PEO / Li -ion complexes and solid-state NMR techniques through the class complex phase structure and molecular motion of systematic research to deepen the class of polyelectrolyte polymer conductive mechanism understanding. Its main contents can be divided into two parts, the first part is mainly prepared by PEO and C60 complexes and studied the complexation between PEO and C60 effect on the ability of PEO molecular crystal ; second part of the work is the preparation of a series of major with a lower content PEO/Li/C60 crystalline compound . Through the wide-angle X-ray diffraction and solid-state NMR techniques that type of complex phase structure and molecular motion studies to analyze such complexes Li -ion , C60 content on PEO molecular complexes capable of crystallization . On this basis , measured by the AC impedance method prepared several PEO/Li/C60 conductivity composites , composites studied and discussed in the various system components of the conductivity of the system .
