Synthesis and Aqueous Dispersion of Monodisperse Magnetic Fe₃O₄ Nanoparticles

Article Preview

Abstract:

Iron oxide (Fe3O4) nanoparticles as one of the most important nanomaterials are suitable for many applications. Monodisperse magnetic Fe3O4 nanoparticles were synthesized by the thermal decomposition of the iron oleate precursor in octadecene (ODE). The iron oleate complex was prepared by reaction between sodium oleic and FeCl3·6H2O at low temperature. The Fe3O4 nanoparticles were transferred from organic solvent into water by amphiphilic copolymer. The aqueous dispersion of Fe3O4 nanoparticles was stable in water and physiological buffers. This method with low cost can be used to prepare large scale of aqueous dispersion of Fe3O4 nanoparticles.
