Abstract

Monodisperse Fe3O4 Nano particles have been successfully synthesized by solvothermal method using water and ethylene glycol as solvents, and their sizes could be controlled by changing the ratio of water to ethylene glycol. Subsequent surface modification of Fe3O4 had been carried out using tetraethyl orthosilicate and 3-Aminopropyl triethoxysilane as modification agents. The magnetic materials have been characterized by scanning electron microscopy, X-ray diffraction and Fourier-transform infrared spectroscopy. It was verified that SiO2 layers have been coated on the surface of Fe3O4 and NH2- groups have been grafted on the spherical surface of magnetic materials.
