反胶束微乳液法制备的Fe_3O_4纳米微粒

Nanometer Magnetite Prepared by Inverse Micelle Microemulsion Method

报道了一种反胶束微乳法制备纳米Fe3O4微粒的方法。以十六烷基溴化铵／正丁醇／正辛烷／氨水构建反胶束微乳液体系，通过反胶束微乳法制备纳米Fe3O4微粒，利用X射线衍射（XRD）、红外光谱（IR）分析、透射电镜（TEM）等对所得产物进行表征和分析。结果表明，制备的产物为单相Fe3O4纳米微粒，粒径均匀，颗粒尺寸集中分布在20～30nm之间，纯度高，分散效果好。

In this paper, inverse micelle microemulsion method was reported for preparing nanometer magnetite particles. First, the bromide/n -Butyl alcohol/n -Octane/NH3·H2O reverse micelle microemulsion system was built, and then the nanometer magnetite particles was gained from the system. The products were characterized by XRD, IR and TEM. The results indicated that high dispersive single-phase Fe3O4 nanometer particles were synthesized with particle size between 20 and 30nm.
