Fabrication and comparative study of magnetic Fe and α-Fe2O3 nanoparticles dispersed hybrid polymer (PVA + Chitosan) novel nanocomposite film

Incorporation of nanoparticles into polymer matrix allows the development of new features that differs from the pure materials. In this research, magnetic nanoparticles reinforced organic biodegradable polymer matrix based biocompatible nanocomposite films were fabricated. This work covered, synthesis of Iron (Fe) and Iron oxide (α-Fe2O3) nanoparticles by chemical reduction and sol-gel method respectively, fabrication of Fe/Polyvinyl alcohol (PVA)/Chitosan and α-Fe2O3/PVA/Chitosan nanocomposites by solvent casting method, and evaluation and comparison of their mechanical properties to find the superior biocompatible nanocomposite. The X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDX) analysis confirmed the size, structure, morphology and formation of Fe and α-Fe2O3 nanoparticles. Magnetic study showed that, synthesized α-Fe2O3 nanoparticle possess better magnetic properties than the Fe nanoparticle.…
