Abstract

Polyaniline–NiFe2O4 nanocomposites (PANI–NiFe2O4) with different contents of NiFe2O4 were prepared via in situ chemical oxidation polymerization, while the nanoparticles nickel ferrite were synthesized by sol–gel method. The prepared samples were characterized using some techniques such as scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Moreover, the electrical conductivity and sensor properties of the nanocomposites were investigated. The SEM images of the composites showed different aggregations for the different nickel ferrite contents. while the thermal analyses indicated an increase in the composites stability for samples with higher NiFe2O4 nanoparticles contents. The electrical conductivity of PANI–NiFe2O4 nanocomposite was found to increase with the rise in NiFe2O4 nanoparticle content, probably due to the polaron/bipolaron formation.
