摘　　要：以柴油为基液制备了纳米磁性液体，并对其进行了相关表征。结果表明：制得的柴油基纳米磁性液体主流粒径为6—8nm，具有很好的磁性能与使用性能；加入表面活性剂的纳米磁性液体，磁性微粒表面形成了无定形包覆层，可保持晶粒完好，晶形稳定，增加了纳米磁性液体的磁性能和稳定性。Nanometer magnetic fluid is prepared by using diesel oil as a base-liquid. It＇s relevant characteristics are tested. The results show that the diameters of most particles got from diesel oil-based nanometer magnetic fluid are 6-8 nanometers and they have good magnetic nature and application. When surface activated substance is added into nanometer magnetic fluid, amorphous covering is formed on the surface of magnetic particulates. As a result, the crystalloid granules can keep good forms, the crystalloid forms remain stable, and the magnetic nature and stability of nanometer magnetic fluid are increased.
