The mixture of iron oxide and reduced graphite oxide (RGO) have been researched by its mixed properties as a filler; aligned thermal fillers in magnetic. Nevertheless, not only is there a high chance of iron oxide-coated RGO agglomerating at neutral PH. In this study, diverse spacers between RGO and iron oxide had been added for better dispersibility and simple production. Varying the molar ratio of FeCl3•6H2O to FeCl2•4H2O, the experiment progressed to compare the influences on the precursor of Fe; α-Fe2O3, γ-F2O3 and Fe3O4. Varied spacers were put onto RGO, iron oxide was located outermost in a row. Scanning and high-resolution transmission electron microscopy were used for the check of the existence of magnetic material on RGO. Thermal gravity analysis was employed for the relative amount of thermal residue, iron oxide in O2 atmosphere. Vibrating sample magnetometer was utilized for magnetic properties. |
