Electrical conductivity of polyaniline doped PVC-PMMA polymer blends

Abstract

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.

A.C Electrical Conductivity for Polyaniline Prepered in Different Acidic Medium

“…These properties are optimal at stoechiometrical ratio between the oxidant, hydrochloric/ sulfuric acid and aniline (da-Silva, et. al., 2005;and Hdeshmukh, et. al., 2007).…”

Charge Transport and Electrical Switching in Composite Biopolymers

“…The current levels in the reverse bias are higher than forward bias. This behaviour may be interpreted either in terms of Poole-Frenkel effect which is due to thermal excitation of trapped charges via field assisted lowering of trap depth or by Schottky effect which is a field lowering of interfacial barrier at the blocking electrode (Deshmukh et al 2007). The expressions for these processes are given in Eq.…”
