摘　　要：双面粒子是指粒子的两个半球表面具有不同组成或性质的微粒。这种各向异性或不对称的结构使其有很广泛的应用,但也使其制备变得困难。近年来已发展了很多制备方法,本文总结了最近几年双面粒子在制备及应用方面的研究进展。The term ＂Janus particles＂is used for the deseription of particles with different compositions or properties on the surface of both hemispheres.Owing to their anisotropic or asymmetric structure,Janus particles have been found extensive applications in many fields.However,the anisotropy or asymmetry also makes it difficult to be prepared.A number of methods have been achieved in recent years.The progress of the preparations and applications of Janus particles were reviewed in this paper.

关 键 词：双面粒子 不对称性 表面 应用
