纳米磁性液体材料的研究进展

Research Progress of Nano Fluid Materials

综述了国内外纳米磁性液体材料的发展现状。磁性液体材料是一种特殊的新型材料,是由磁性纳米微粒(一般要求小于10nm)均匀弥散于某种液体基液中所构成的稳定体系。同时具有磁性和流动性,因此具有许多独特的磁学,流动力学,光学和声学特性。系统介绍了目前纳米磁性液体材料根据纳米磁性液体材料中的铁磁性固体颗粒的不同的分类及纳米磁性液体材料的基本性质。最后综述介绍了纳米磁性液体依据其独有的特殊性能和其在化工环保、印刷制造、医疗卫生、仪器仪表、航天航空中典型应用。同时比较了国内外纳米磁性液体材料的发展状况。

The research progress of nano magnetic fluid is reviewed.Magnetic material liquid material is a special kind of nanostructure magnetic material which consists of colloidal suspension of tiny （about 10 nm）magnetic particles suspended in a carrier liquid.It is magnetic and mobile, therefore has many special peculiarities of magnetism, liquid kinematics, optics and acoustics.It introduced the classification of nano magnetic fluids in different standards, and the different way of making it.And then the basic character of Magnetic fluids is introduced in details.At last,as an example,there is a typical application of nano magnetic fluid magnetic.In this text,by which this special material is described more clearly.Simultaneously has compared the domestic and foreign nanometer magnetic liquid material development condition.
