Synthesis and characterization of polyaniline coated functionalized g-Fe O nanoparticles

Polymer coated nanoparticles have been studied for electrical, optical,
electrochemical devises, sensors and other biomedical applications due to change in their
physical and chemical behavior. Polyaniline coated g-Fe O nanoparticles gave new 2 3
approach to research in sensors. In the present paper we synthesized polyaniline coated
functionalized g-Fe O nanoparticles (PaCFNPs) through in situ doping polymerization 2 3
in the presence of HCl as dopant. The obtained nanoparticles were characterized,
employing XRD pattern through X-ray diffractometer, molecular structure through
FT-IR spectroscopy, magnetic property by B-H loop tracer, thermal (TGA/DSC) study
by thermal analyzer and surface morphology by SEM. Through the mentioned
characterizations we obtained superparamagnetic PaCFNPs.
