Preparation and characterization of polyaniline-cobalt ferrite nanocomposite applicable as a microwave absorber coating

In this restructure CoFe2O4 nanoparticles were first synthesized via precipitation method by various natural capping agents such as lactose, glucose and sucrose. Then CoFe2O4 / poly aniline nanocomposites then were prepared using an easy polymerization method in low temperature for surface coating of military equipment (invisible they radars) for microwave absorber and obviation it. The prepared products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectroscopy. Magnetic property studies of the products were carried out using an alternating gradient force magnetometer (AGFM) and the results illustrated super- paramagnetic behavior of CoFe2O4 nanoparticles.
