Graphene oxide–magnetite nanoparticle composite has recently become a hot topic in various fields such as MRI, drug delivery, battery, and removal of heavy metal from waste water. Many researchers utilized precursors such as FeCl2, FeCl3 for synthesizing magnetite nanoparticle in Graphene oxide solution in composite fabrication, where the particles tightly bind to hydroxyl or carboxyl groups on GO during the synthesis. In this study, we investigate a quick method for graphene oxide – magnetite nanoparticle composite formation without chemical processes. This method is easier to control particle size and its distribution and cost-effective compared to the synthesized one. The attachment of the nanoparticle on GO surface was confirmed by TEM, SEM, FTIR, Raman, UV-vis, XRD, TGA, and AFM. The composite was foune to be mechanically stable against repetitive agitation, which may be comparable to the synthesized one. As an example of its application, its heavy metal ion scrubbing ability will be presented. |
