Materials are usually classified as solids or liquids, based on their structural stability, dynamic response, and rheological properties. Structured liquid, a new state of matter, has attracted much attention in recent years. Different with either solid or liquid, structured liquid combines the desirable characteristics of fluids with the structural stability of a solid, showing a myriad of potential applications in encapsulation, biphasic reactors, and programmable liquid constructs. Here, a brief review is given, by introducing a new strategy to structure liquids based on the formation, assembly, and jamming of nanoparticle surfactants (NPSs) at liquid-liquid interfaces. The interfacial packing of the NPSs can be effectively manipulated using external triggers, endowing the structured liquids with adaptiveness and responsiveness to changes in their external environment.

纳米颗粒表面活性剂和结构化液体

根据材料的结构稳定性、动态响应和流变特性，材料通常分为固体或液体。结构液体作为一种新的物质状态，近年来备受关注。与固体或液体不同，结构化液体结合了流体的理想特性和固体的结构稳定性，在封装、双相反应器和可编程液体结构中具有无数潜在的应用。在这里，通过介绍一种基于纳米颗粒表面活性剂 (NPS) 在液-液界面上的形成、组装和阻塞来构造液体的新策略，给出了一个简短的回顾。NPS 的界面堆积可以使用外部触发器有效地操纵，
