Abstract
Iron oxide nanoparticles (NPs) have potential in biological, biomedical, and environmental applications because of their magnetic susceptibility, stability, and biocompatibility characteristics. However, it also has limitations, such as the aggregation of magnetic NP. Thus, the outer surface of the particles should be modified by coating materials. This paper focused on synthesizing iron oxide by chemical reduction method and coating it with Fe(III) nitrate, PVP, and hydrazine. The coating solution at two different concentrations was prepared to determine effective and economical usage conditions. The effect of coating iron oxide with microcrystalline cellulose (MCC) was conducted at different concentrations of iron oxide on the nanomaterials with respect to morphological, thermal, and magnetic susceptibility. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicated good morphology images of FeNp-MCC. Energy dispersive X-ray (EDX) spectra reveal the presence of carbon, oxygen, and iron in the synthesized microparticles.TGA analysis showed iron material was succesfully formed into the surface of microcrystalline cellulose. Lastly,the magnetism results proved that cellulose is strongly interacting with magnetite nanoparticles.
