Study of DC electrical properties of iron oxide doped polyaniline

Abstract

The oxidative polymerization process has been used to prepare composites of Polyaniline/iron oxide (PANI/Fe2O3). For synthesis of these composites, Polyaniline using different amounts (10, 20, 30, 40, 50 wt %) of the Fe2O3 with oxidant ammonium persulphate have been used. Temperature dependent dc conductivity measurement is done in temperature range upto 120°C using Mott’s model. Mott’s model explains the conduction by hopping process in disordered semiconducting systems and match well with the experimental data.
