Anisotropic polaron motion in polyaniline studied by muon spin relaxation

Abstract:: Muon spin relaxation has been used to probe the highly anisotropic motion of polaronic charge carriers in the emeraldine base form of polyaniline. The measured diffusion rate along the polymer chain for negative polarons shows a metalliclike temperature dependence, which is saturated at low temperatures but becomes limited by phenylene ring librational scattering above 150 K. The interchain transport at room temperature is more than 4 orders of magnitude slower than the intrachain process and becomes further suppressed on cooling.
