| Abstract: | Fe3O4/ chitsosan （Fe3O4/ CS） nanocomposites have magnetic property and particular functional groups reacting with bioactivator, which enables Fe304 / CS nanocomposites to be used as carrier of bioactivator and has odegradability. The preparation methods of Fe3O4/ CS nanocomposites, including the co-precipitation method, the adsorption method, the emulsification crosslinking method and the in situ-precipitation method, were reviewed in detail. Meanwhile, the advantages and disadvantages of different preparation methods were compared. The application status and prospect of Fe3O4/ CS nanocomposites in biomedicine, water treatment, food industry and other fields were introduced. |
