Abstract : Polymer nanocomposites have been studied due to change in their physical and chemical behaviour when doped with nanoparticles. They are used in electrical, optical, electrochemical devises, sensors and other biomedical applications. γ-Fe2O3 nanoparticles dispersed polyaniline - Polyvinyl alcohol (PVA) nanocomposites have increased attention due to its applications for making capacitors and sensors. In the present work we synthesized γ-Fe2O3 dispersed functionalized polyaniline -PVA nanocomposites (FPNC) film, an interpenetrating polymer network (IPN) through in situ doping polymerization in the presence of HCl as a dopant. The synthesized FPNC film were characterized, employing powder XRD through X-ray diffractometer, molecular structure through FT-IR spectroscopy, thermal (TGA/DSC) study by thermal analyzer, surface morphology is studied using SEM and DC conductivity measured employing four probe Keithely high precision multimeter. All the characterizations confirmed the obtained FPNC film is a stable interpenetrating polymer network. The synthesized film FPNC envisioned for making capacitors and sensors.
