本研究从改进磁流体的制备方法入手,很好地解决了磁流体中Fe_3O_4粒子的聚团问题,并利用表面活性剂对Fe_3O_4粒子进行单独或复合包覆处理制备出了高稳定性的油基、水基及聚醚基磁流体。
In this study, starting from improving the preparation method of magnetic fluid, the problem of agglomeration of Fe3O4 particles in the magnetic fluid was solved well, and the high stability of the oil base was prepared by using the surface active agent alone or in complex coating with Fe3O4 particles , Water-based and polyether-based magnetic fluids.
