Synthesis and remarkable microwave absorption properties of amine-functionalized magnetite/graphene oxide nanocomposites

We prepared magnetite nanoparticles by co-precipitation method and functionalized them by amine groups prior to hybridization with graphene oxide. The resulting nanocomposites Fe3O4-NH2/GO were prepared with three weight ratios: 1:1, 2:1, 3:1, [Fe3O4-NH2:GO], in order to compare their magnetic properties. We used different techniques to investigate the nanocomposites: Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron...
