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.
