Parallel conductivity of polyaniline (leucoemeraldine base) and its dependence on temperature based on the conduction electron density
Abstract
Conduction electron density and carbon-carbon length were determined to get the parallel conductivity of undoped and several doped polyaniline (PAni) leucoemeraldine base. The dopants used were hydrochloric acid (HCl), nitric acid (HNO3) and sulfuric acid (H2SO4). Carboncarbon lengths were computed using PM 3 semiempirical method. The behaviors of the conductivity with the conduction electron density and temperature were determined. Doped PAni showed higher conductivity compared to its undoped form. Carbon-carbon length and conduction electron densities could be used to evaluate parallel conductivity but is limited in distinguishing the conductivity among the doped forms of PAni.
