A Perspective on Electrochemical Impedance Analysis of Polyaniline Films on Electrodes

摘要

During the past two decades,extensive studies of conductive polymers have been driven by their special properties such as flexible solution and melt processability manufacturing,blendability with commodity polymers,good ambient stability,and unconventional electrical and optical properties.The most valuable property of these materials is their unique ability to dramatically and reversibly change electrical conductivity over a full range-from insulators to metallic conductors-upon partial electrochemical oxidation or reduction,a process commonly referred to as"doping."
