Paper Title:
Preparation and Characterization of Water Based and Double Enveloped Nano-Fe3O4 Magnetic Fluids
  Abstract

The nanoparticles of Fe3O4 were prepared with chemical precipitation method, and then used sodium oleate and the lauryl sulfonic aid sodium as bilayer to envelope the ultra-fine Fe3O4 particles. Then stabilized water base magnetic fluid was obtained. The crystallization behavior and the surface of Fe3O4 nanoparticles after the modification were investigated with XRD and IR respectively; the particle size was studied with TEM; the magnetic properties were studied with VSM. The mechanism of bilayer surfactants that modified Fe3O4 magnetic nanoparticles was explained, and influencing factors of the magnetic fluid were discussed.
