ABSTRACT:In this article, a study of the aging of conducting Polyaniline-Polystyrene blends using X-ray photoelectron spectroscopy (XPS) and UV-visible-near IR analysis is presented. The physicochemical results are compared to those obtained by electrical measurements. XPS results confirm the existence of an oxidation process also deduced by the electrical conductivity studies. The N1s and S2p core level spectra decomposition allows to show that a deprotonation process and cyclization of tertiary amine occur during aging. The absorption spectrum shows a decrease of delocalized charges and the apparition of localized polarons after a long aging time. All these mechanisms are responsible of the electrical conductivity decrease observed during aging at elevated temperature. The results are presented for films of PANI-CSA-PSt blends, but the conclusions can be extended to pure conducting PANI-CSA films.

ABSTRACT:In this article, a study of the thermal behavior of polyaniline films and polyaniline-polystyrene blends is presented. Transport measurements (electrical conductivity and thermoelectric power) at high temperature and thermogravimetric analysis show that an irreversible degradation is observed near 450 K for films doped with DiOHP and near 500 K for films doped with CSA. In both cases, the thermoelectric power is the most sensitive parameter to electrical degradation during the heating of conducting films. Electrical conductivity measurements during heating-cooling cycles show a diminution of the room temperature conductivity after evaporation of the solvent (water, m-cresol). A model of cluster with a variable diameter allows interpreting this phenomenon by assuming the existence of a sensitive frontier to the solvent at the periphery of conducting clusters.
