含聚氧化乙烯侧链的聚合物凝胶电解质的动态力学性能和离子导电性

Dynamic Mechanics and Ion Conductivity of Cmblike Polymer Gel Electrolytes

红外测试结果表明产物是含聚氧化乙烯侧链的聚合物。该聚合物电解质的室温电导率为10-3S/cm数量级。并用动态力学方法,研究了分子链段活动性与聚合物凝胶电解质组成(增塑剂含量、含盐量和盐种类)的关系。

A comblike gel polymer electrolyte was synthesized. IR spectroscopic measurements indicated that the structure of the comblike polymer was in accord with what we designed. The conductivity of the comblike polymer electrolyte prepared at room temperature is at magnitude range of 10^-3 S·cm^-1 . The relation between the molecular segment movement and the composition (i.e. the content of plasticizer, the content of salt and kinds of salts) of comblike polymer gel electrolytes was studied by the dynamic mechanical method. Polymer gel electrolytes with good mechanical properties were obtained.
