Made to order: Aqueous dispersions of polymer-encapsulated liquid crystal (LC) droplets were synthesized with precise interfacial chemistry and sizes in the micrometer-to-sub-micrometer range. Size-dependent changes in LC ordering could be observed. Study of the competition between size and interfacial chemistry on LC ordering enables size-dependent properties of LC droplets to be exploited in applications such as photonics and sensing.
定制合成
采用精确的界面化学方法合成了聚合物包裹液晶（LC）微滴的水分散体，其尺寸范围为微米至亚微米。可以观察到液晶有序性随尺寸的变化。研究尺寸和界面化学对液晶有序性的竞争关系，有助于在光子学和传感等应用中利用液晶微滴的尺寸依赖性特性。
