Byusing FT IR, TG, XRD and TEM, the resultant surface modified Ni particles were characterized. The results show that the nano Ni core has an average diameter of 12nm with a fcc structure. The hydrophobic groups formed by the organic layer on the surface of Ni particles make the nanoparticles have good stability andoil solubility.展开更多
