A magnetic susceptibility investigation of emeraldine base polyaniline

摘要

Magnetic susceptibility measurements are reported on samples of emeraldine base polyaniline synthesized at five oxidant/monomer ratios in the range 0.25-1.45. Analysis of the magnetic susceptibility data in the temperature range 77-475 K, along with our dielectric and ac conductivity measurements at room temperature, reveals increased disorder with increase in the oxidant/monomer ratio.
