摘要
纳米磁性流体是诞生于 2 0世纪 60年代末的一种新型的液体功能材料 ,是一种纳米铁磁性微粒在表面活性剂的包覆下 ,稳定地分散在载液中而形成的一种胶体 .介绍了它的磁性、黏度特性、蒸发特性和温度特性等几种主要性质、典型的制备技术以及它在密封、润滑、阻尼、研磨、印刷、医学等方面的应用和发展 ,并提出了值得重视的研究领域以及对纳米磁性流体研究的几点建议 .
Nanoferrofluid is a new kind of liquid functional material developed in 1960's. It is a colloid formed by ferromagnetic nano particles which are coated with surfactant layer stably dispersing in a liquid carrier. The characteristics of nanoferrofluid, its preparation methods and applications in seal, lubricating, damping, grinding, printing and medicine fields are reviewed. Some suggestions of our research in future are proposed.
