Application of Microwave Cavity Perturbation Techniques in Conducting Polymers

Abstract

Microwave cavity perturbation (MCP) techniques have been applied to measure complex microwave conductivities of conducting polymers. We find MCP is suitable for polymers with a large range of conductivities. In our experiment it is possible to determine the parameter within 5% for fairly conducting samples through the extrapolation of normalized frequency shift to the high conducting limits (i.e., high temperature limit) and/or the comparison with DC conductivity. For all cases the experimentally determined values are very close to the calculated ones based on the measurement of sample geometry. Some potential microwave applications of the conducting polymers are discussed.
