CoFe2O4 Magnetic Nano Particles (MNPs) were synthesized by an efficient method in aqueous medium with the particle sizes of about 20-50 nm. Then, a hybrid nanocomposite of polyaniline (PANI)-CoFe2O4 MNPs has been electrodeposited directly on a stainless steel wire by the potentiostatic method. Microscopic images of electrodeposited PANI and PANI-CoFe2O4 nanocomposite coatings were obtained by scanning electron microscope. The scanning electron microscopic images of polyaniline and its nanocomposite pointed out the influence of CoFe2O4 nanoparticlesin the electrodeposition of polyaniline. Dispersion of CoFe2O4 nanoparticles in electrolyte solution during the electrodeposition, creates a nanocomposite with a more surface area than pure polyaniline.
