水基磁流体的制备与性质研究

Study on preparation and properties of water-based magnetic fluid

采用十二烷基硫酸钠进行磁性颗粒的二次改性 ,通过胶溶法制备稳定的水基磁流体。应用X -ray衍射仪、透射电镜对磁性颗粒的结构、粒径、形貌进行了表征 。

This article introduces the preparation of stable water-based magnetic fluid by the way of gel with using C 12 H 25 OSO 3Na.The characters are analysed by X-ray and TEM,and the effects produced by preparation conditions on the properties of water-based magnetic fluid are discussed in this paper.
