| 摘 要： | 采用共沉淀法制备Fe_3O_4磁流体,以十二烷基磺酸钠为分散剂进行第一包裹,再以亲水性更强的聚乙二醇进行第二次包裹,理论上先制取粒子再包裹的方法,制得稳定性较高的水基磁流体,能稳定存在较长时间。通过红外光谱、磁光效应、热稳定性对所制产物进行了初步的表征。

| Abstract: | The Fe3O4 magnetic fluid was prepared with altogether the precipitation, and then used the lauryl sulfonic acid sodium and the polyglycol as the agent to enwrap the Fe3O4 magnetic fluid. The characters of the receiving product were higher and longer stability. The product was characterized by using the IR, the magneto-optical effect and the thermo stability. |
