This study modifies iron oxide (Fe3O4) magnetic nanoparticles (MNPs) by polyethylene glycol (PEG) and polyvinyl alcohol (PVA) coating co-precipitation method. MNPs were characterized by XRD, FTIR, TEM, DLS, and VSM analyses to study their structure, morphology, and magnetic properties. The results showed the superior properties of PEG and PVA-coated Fe3O4 compared to the pristine sample. It is illustrated that modified Fe3O4 MNPs improved magnetic saturation. The particle size of PEG-coated Fe3O4 nanoparticles was estimated at 11 nm with magnetic saturation of 60.98 emu/g and coercivity of 8.26G.
