Microwave Synthesis and Magnetic Investigation of CuFe2O4 Nanoparticles and Poly Styrene-Carbon Nanotubes Composites

At the first step CuFe2O4 nanoparticles were synthesized by a fast and facile microwave method. The obtained nanoparticles and modified carbon nano tubes were added to poly styrene matrix. The products were characterized through Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. Vibrating sample magnetometer shows nanoparticles exhibit ferromagnetic behavior. The influence of CuFe2O4 nanostructures on the flame retardancy of the polystyrene (PS) matrix was studied using UL-94 analysis. The enhancement of thermal stability and flame retardancy of nanocomposites is due to magnetic CuFe2O4 barrier against flame, oxygen and evaporation.
