The electrical conductivity of polyaniline doped polyvinylchloride (PVC) and poly(methyl methacrylate) (PMMA) thin films has been measured by studying the I–V characteristics at various temperatures in the range 323–363 K. The results are presented in the form of I–V characteristics and analysis has been made by interpretation of Poole-Frenkel, Fowler-Nordheim, Schottky ln(J) vs T plots, Richardson and Arrhenius plots. The analysis of these results suggests that Schottky and Richardson mechanisms are primarily responsible for the observed conduction.
