Abstract
We report the results of transport studies (temperature-dependent d.c. conductivity, thermopower, microwave frequency conductivity and dielectric constant for camphor sulfonic acid-doped polyaniline (PAN-CSA) and its methyl ring-substituted derivative, poly(o-toluidine) (POT-CSA) fibers prepared in solutions of m-cresol. The results for the PAN-CSA fiber are very similar to those for PAN-CSA film with the presence of some poorer conducting linkages. The POT-CSA fiber shows significantly higher conductivity with much weaker temperature dependence than the earlier studied hydrochloric acid-doped poly(o-toluidine) (POT-HCl) fiber and powder, indicating that it is much closer to the localization-delocalization boundary.
