Janus粒子制备研究进展

摘要

按照Janus粒子制备原理,以本体相非对称化、表面非对称性修饰及非对称性混合法对两半具有截然不同性质的粒子——Janus粒子的制备研究进行了综述,并对文献中所涉及的制备方法和相应方法的局限性进行了讨论.这种分类使多样化制备方法有更明确的本质定位和丰富的包容性.同时对材料功能需求及Janus粒子满足功能需求的制备方法改进等进行了展望.%Janus particle is a kind of particle which has two parts with deferent property. The feature of this particle makes it use in construction of various structural materials. According to the preparation principles, the preparation methods including bulk phase-based asymmetry, asymmetry modification of surface and asymmetry blend, are reviewed. This classification makes the involved methods more specific and more comprehensive. The future requirements in preparation of functional materials and the preparation methods to meet these requirements are prospected.
