摘　　要：纳米磁性液体是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,在工业领域得到广泛的应用。文章概述了纳米磁性液体的组成、制备技术、基本特性、应用以及当前研究进展,着重阐述了纳米磁性液体在防伪印刷以及快速射流印刷中的应用前景。Nanometer magnetic liquid is a kind of colloid system which is formed by nanometer ferromagnetism particles enwrapped by surfactant and disperse steadily in the liquid, it is magnetic and mobile, therefore has many special pecu liarities of magnetism, liquid kinematics, optics and acoustics, and widely used in the industry. This paper summarize the component in the liquid, preparation technology, basic properties, application and current research of nanometer magnetic, and focus on the application prospect in the antiforgery printing and high-speed fluidic printing of nanometer magnetic liquid.
