摘要: 制备了室温电导率较高(10-4S•cm-1),力学性能较好的环氧乙烷和环氧丙烷共聚物-Li-ClO4复合物薄膜,研究了共聚物组成对结晶及对复合物室温电导率的影响,考察了高氯酸锂浓度对复合物室温电导率的影响以及复合物电导的温度依赖关系,发现复合物中没有结晶配合物,其结晶度随聚合物结构和盐含量不同而变化,室温下呈弹性体。

Abstract: The title copolymer was prepared and characterized by 1HNMR, DSC, and mechanical property measurements. The sample appeared to be an elastomer at room temperature. The effects of the EO/PO ratio and LiClO4 content of the copolymer-LiClO4 complex on the crystallinity and conductivity have been studied. The conductivity of the LiClO4 dopped copolymer film was 1.2?10-4S/cm at room temperature obtained from AC impedance.
