Paper Abstract

The excess amount of oleic acid must be added to synthesize the bilayer oleic acid-coated Fe3O4 nanoparticles by onestep method. To know the evolution of surface structure during removing the residual oleic acid by ethanol washing, the surface structure of bilayer oleic acid-coated Fe3O4 nanoparticles synthesized by one-step method was studied using TEM, FTIR and TGA with washing times. The results showed that after five times washing, the bilayer oleic acid-coated structure still remained; after twenty times washing, the bilayer oleic acid-coated structure evolved into the single layer one.
