| Abstract: | Fe3O4 nanoparticles with 2nm size were synthesized by high temperature thermal decomposition method. The nanoparticls were modificated with the surfactant of oil-acid. The synthesized nanoparticles were characterized by TEM,VSM,XRD and FT-IR. The results show that Fe3O4 nanoparticles are monodisperse, good crystalline performance, superparamagnetic and the saturation magnetization is 11.73emu/g in room temperature, which could be applied in magnetic fluids, magnetic separation and other fields. |
