| 摘 要： | 以柠檬酸为改性剂，制备水基Fe3O4磁性纳米粒子，基于静电自组装作用，使壳聚糖分子在水溶液中包覆Fe3O4纳米晶粒，获得壳聚糖/Fe3O4复合纳米颗粒液溶胶。扫描电子显微镜（SEM）分析结果表明，复合纳米颗粒平均粒径为49.0 nm，标准差为11.0 nm。X射线衍射（XRD）和红外光谱（FT-IR）分析结果表明，复合纳米颗粒由壳聚糖分子和Fe3O4晶体粒子构成。

| Abstract: | The magnetic fluid was prepared by modifying the surface of F% 04 nanoparticles with citric acid. These Fe3O4 nanoparticles encapsulated by chitosan molecules through electrostatic force could be readily dispersed in aqueous solution. It was found in the SEM image that the aver- age diameter of nanocomplex was 49.0 nm, standard deviation was 11.0 nmo The particles prepared from chitosan and Fe3O4 were characterized by XRD and FF- IR nanocomplex analysis. |
