The magnetic nanoparticles were then added to acrylonitrile-butadiene-styrene, polystyrene, polycarbonate, and poly sulfone to make magnetic nanocomposites. The magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. The strontium ferrite nanoparticles exhibited ferrimagnetic behaviour at room temperature, with a saturation magnetization of 39 emu/g and a coercivity of 5070 Oe. The distribution of the SrFe12O19 nanoparticles into the polymeric matrixes increases the coercivity.

The magnetic nanoparticles were added to starch to make magnetic polymeric nanocomposite. The nanoparticles and nanocomposites were characterized using X-ray diffraction and scanning electron microscopy. The magnetic properties of the samples were investigated using an alternating gradient force magnetometer (AGFM). The copper ferrite nanoparticles exhibited ferromagnetic behavior at room temperature, with a saturation magnetization of 29emu/g and a coercivity of 136 Oe. The distribution of the CuFe2O4 nanoparticles into the polymeric matrixes decreases the coercivity (136 Oe to 66 Oe). The maximum coercivity of 82 Oe was found for 15% of CuFe2O4 distributed to the starch matrix.

BaFe nanoparticles were then added to acrylonitrile-butadiene-styrene (ABS) and cellulose acetate (CA) in order to make magnetic nanocomposites. Nanoparticles and nanocomposites were then characterized using X-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. The barium ferrite nanoparticles exhibit ferrimagnetic behaviour at room temperature, with a saturation magnetization of 53 emu/g and a coercivity of 2430 Oe. Distribution of the BaFe12O19 nanoparticles into the polymeric matrixes increases the coercivity dramatically.
