| 摘 要： | Nano-sized Fe3O4 powder was prepared through an Oxygenation-Hydrothermal method. The chitosan magnetic complex was prepared by coating chitosan on the surface of Fe3O4 powders through Microlatex-Crosslinking Method. The product was characterized by IR， XRD， TEM， Vibrating Sample Magnetometer (VSM)， TG methods. Results show that the as-prepared powder is 25 nm in size and shows supermagnetism. The content of magnetite in microspheres is 37.8%. The mechanism for the coating reaction of chitosan to Fe3O4 nanoparticles is also suggested.
