摘　　要：四氧化三铁/壳聚糖(Fe3O4/CS)纳米复合材料既具有磁响应功能,还具有与生物活性物质反应的特殊功能基团,可以作为生物活性物质的载体,具有生物可降解性。本文综述了Fe3O4/CS纳米复合材料的制备方法,如化学共沉淀法、表面吸附法、乳化交联法、原位沉析法,并分析了各种制备方法的优点和不足。简单介绍了Fe3O4/CS纳米复合材料在生物医学、水处理和食品工业等领域的应用现状和应用前景。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.
