摘要
用化学沉淀法制备Fe3O4 纳米粒子 ,以十二烷基磺酸钠 ,蓖麻油 ,油酸钠为分散剂 ,制备水基Fe3O4 磁流体 ,研究了搅拌时间对磁流体的磁性能的影响 ,表面活性剂用量对磁流体的沉降稳定性的影响 。
The nanometer Fe 3O 4 was successfully prepared by chemical deposition method and stable water-based Fe 3O 4 magnetic fluid was successfully prepared by adding appropriate surfactant such as Dodecyl sulfonic acid sodium,Castor oil,Sodium oleate.Study and illuminate why the quantity of surfactant and the length of stirring time affect the character of the Aqueous Ferrofliud.
