摘　　要：介绍了共沉淀法、水热法、微乳液法、溶胶-凝胶法、胶体粒子模板法、多元醇还原法和置换法等合成磁性纳米粒子的方法及特点,概述了磁性纳米粒子的表面改性和表征方法,对纳米磁性粒子的研究前景进行了展望。Nano-magnetic particles are constructured with magnetic transition metal or alloy nano-particles embedded in non-metallic medium, which contain the advantages of two types of material. Nano-magnetic particle is a multi-functional magnetic material and has wide applications in many fields, such as magnetic recording, ferrofluids, catalysis, medicine and pigment. In this paper, some items about nano-magnetic particles were introduced. Firstly, the preparation methods including precipitation, hydrothermal method, micro-emulsion, sol-gel, colloidal particles template, polyol reduction method, displacement method and characteristics of nano-magnetic particles were introduced. Secondly, the surface modification methods and characterization of nano-magnetic particles were described. Finally, the research prospect of nano-magnetic particles was presented.
