The Influence of Inorganic Material on Electrical Conductivity of BPDA-ODA/ LiClO4 System

Abstract

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.

Key words: polymer electrolyte, polyimide, ionic conductance, silica
