摘要

The surface organic modification of Fe₃O₄ nanoparticles with silane coupling reagent KH570 was studied. The modified and unmodified nanoparticles were characterized by FT-IR, XPS and TEM. The spectra of FT-IR and XPS revealed that KH570 was coated onto the surface of Fe ₃O₄ nanoparticles to get Fe-OSi bond and an organic coating layer also was formed. Fe₃O₄ nanoparticles were spheres partly with mean size of 18.8 nm studied by TEM, which was consistent with the result 17.9 nm calculated by Scherrer's equation. KH570 was adsorbed on surface and formed chemistry bond to be steric hindrance repulsion which prevented nanoparticles from reuniting. Then glycol-based Fe₃O ₄ magnetic liquids dispersed stably was gained.
