Abstract:Nano-size Fe3O4 particles with superparamagnetic magnetism were prepared by coprecipitation without N2. The magnetic chitosan composite nanoparticles modified by carboxyl have been prepared by inverse suspension polymerization method. Magnetic chitosan nanospheres were prepared using the inverse phase emulsion dispersion and chemical crosslinking technology，and then modified with ethylenediamine. The products were characterized.
Key words: magnetic chitosan; nanoparticles; preparation
