回顾了若干能够将流体交界面拉伸至微米及更小尺度的毛细流动,这些流动类型已经成为制备单分散性微-纳粒子技术的基础,这些技术正引起人们的关注,它们既能制造简单结构的粒子,也能制造核-壳结构的粒子(微纳胶囊、同轴纳米纤维以及中空纳米纤维),而且能够精确地控制粒子的平均尺寸,本文还评述了流动的基本物理以及控制这些毛细流动的无量纲参数.此外,文中还给出一些实例,介绍利用几种装置制备的不同类型粒子. A review of several capillary flows that can extend the fluid interface to microns and smaller scales has become the basis for the preparation of monodisperse micro-nano particle technologies that are attracting attention because of their simplicity of manufacture The structure of the particles, but also can produce core-shell structure of the particles (micro-nano capsules, coaxial nanofibers and hollow nanofibers), but also to precisely control the average size of the particles, this article also comments on the flow of basic physics and control of these capillaries In addition, some examples are given to illustrate the different types of particles prepared using several devices.
