壳聚糖分子中含有大量的官能基团如氨基、羟基，从而具有良好的吸附性能。若在壳聚糖中引入磁性物质，则壳聚糖材料在外加磁场条件下易于同介质分离，并且所得磁性材料还能保留壳聚糖自身的特性。本论文以此为出发点，选用铁离子溶液为磁性Fe3O4源并将其与壳聚糖溶液混合，以氨水为沉淀剂，通过一步沉淀法制备磁性壳聚糖微球(magneticchitosansphere，MCSS)；采用反相乳液法，将氨水溶液首先分散，再加入上述混合溶液制备微米级的中空磁性壳聚糖微球(hollowmagneticchitosansphere，H-MCSS)；利用壳聚糖络合铁离子的性能，用氨气熏蒸法制备磁性壳聚糖杂化材料(hybrid...Abstract Chitosan (CS) has excellent adsorption performance because of the large amount of functional groups such as amino and hydroxyl groups of the macromolecule. If magnetic component was introduced into chitosan material, the composite material could not only retain the characteristics of chitosan, but also be easily isolated from the adsorption medium under a magnetic field. Therefore, Fe2+ ...学位：理学硕士院系专业：材料学院材料科学与工程系_高分子化学与物理学号：2072008115057
