Electrode Polarization and Interfacial Polarization in Composite of Ion conductive Polymer and PZT particles

이온전도성 고분자와 PZT미립자의 복합체에 있어서 전극분극과 계면분극 현상

Dielectric and conductive spect frequency spectra in a $1Hz{\sim}13MHz$ range have been measured for the composite consisting of PZT inclusions dispersed in a $LiClO_4$ doped polyethylene oxide(Li_PEO) matrix with various volume fractions. The dielectric and conductive spectra of the composites revealed the relaxations related with electrode polarization and interfacial polarization The observed spectra were reproduced using the empirical function and we could obtain vairous parameters related to electrode polarization and interfacial polarization.
