Synthesis and Study of Superparamagnetic (Fe3O4/ (Chitosan/alginate)-co-acrylic acid) Nanocomposite for Different Applications

PP: 5-10
Faten Ismail Abou El Fadl,
In this article we report about the synthesis of superparamagnetic bare Fe3O4 nanostructures, (ALG/Chit/Fe3O4), and (ALG/Chit-co-AAc/Fe3O4) nanocomposites. The structural morphology and magnetic behavior of Fe3O4 nanostructures, (ALG/Chit/Fe3O4) and (ALG/Chit-co-AAc/Fe3O4) nanocomposites beads have been investigated by X-ray diffractometer (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). The particle size was calculated by TEM measurements and it turns out to be 12.62, 6.9 and 5.5 nm for bare Fe3O4 nanoparticle, (ALG/Chit/Fe3O4) and (ALG/Chit-co-AAc/Fe3O4) nanocomposites beads, respectively. The synthesized Fe3O4 nanoparticle, (ALG/Chit/Fe3O4) and (ALG/Chit-co-AAc/Fe3O4) nanocomposites beads were found to be super parmagnetic in nature at room temperature.
