Synthesis, Characterization, Thermal Stability and Magnetic Properties of Nanocomposite Films of ABS and Iron Oxide Nanoparticles

Iron oxide nanoparticles (FNPs) synthesized by co-precipitation were used to prepare a nanocomposite with acrylonitrile-butadiene-styrene polymer (FNPs/ABS). The structure and particle size of the FNPs and FNPs/ABS nanocomposite were characterized by X-ray diffraction (XRD). The obtained nanopowders have a spherical structure and a particle size of approximately 3.5 nm as determined by transmission electron microscopy (TEM). The band gaps of the FNPs and FNP/ABS nanocomposite were estimated by UV-Vis spectroscopy. Vibrating sample magnetometry (VSM) was used to investigate the magnetic properties of the FNPs and FNPs/ABS nanocomposite. The FNPs and the FNPs/ABS nanocomposite were found to exhibit superparamagnetic behaviour: the coercivity (Hci) of the FNP/ABS nanocomposite (36.604 G) is higher than the coercivity of pure FNPs (24.810 G). Thermal stability testing showed that the residual weight percent of pure ABS after heating to 800 degrees C was enhanced by adding 10% nanofiller.
