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

Abstract

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°C was enhanced by adding 10% nanofiller.
