摘要： 采用线型缩聚法合成了BPDA－ODA／LiClO4高分子快离子导体．并在其中加入无机物质作比较．用交流阻抗谱法测定了共聚物薄膜的电导率．结果表明：无机物质种类对该系统电导率的影响大于颗粒度对电导率的影响．添加SiO2，不论其颗粒度为0．96μm或是＜0．1μm，都能使该系统200℃的电导率提高一倍左右．

Abstract: A polymer ionic conductor, containing bis(3,4-dicarboxyphenyl) ether dianhydride (BPDA), 4-aminophe-nyl ether (ODA), lithium perchlorate and inorganic material was
synthesized by linear condensation polymerization method. A. C. complex impedance method was used to determine the electrical conductivity of copolymer films. The results
show that the influence of inorganic material kind on conductivity of the system is greater than that of grain size. Adding SiO2 either 0.96μm or <0.1μm, into BPDA
-ODA/LiClO4 system, the electrical conductivity of copolymer at 200℃ is about two times over the original.
