固定在流体界面上的胶体颗粒的应用范围从皮克林乳液和泡沫到通过Langmuir-Blodgett沉积的2D材料的开发。虽然胶体几乎可以有任何大小、形状和化学性质，但颗粒表面形貌或粗糙度最近作为控制界面钉钉、毛细管相互作用、组装和颗粒单层力学的设计参数重新引起了人们的兴趣。在这篇综述中，我们强调了关于流体界面粗糙胶体粒子的基础科学，以及如何操纵粗糙度可以成为材料设计的工具，而不仅仅是需要处理的特征。虽然现有的工作揭示了粗糙度的重要性，但该领域仍处于起步阶段，因此本综述强调了未来研究的挑战和机遇。
Colloidal particles pinned to fluid interfaces have applications ranging from Pickering emulsions and foams to the development of 2D materials via Langmuir-Blodgett deposition. While colloids come in virtually any size, shape, and chemistry, particle surface topography, or roughness, has recently found renewed interest as a design parameter for controlling interfacial pinning, capillary interactions, assembly, and mechanics of particulate monolayers. In this review, we highlight the fundamental science regarding rough colloidal particles at fluid interfaces and how manipulating roughness can be a tool for material design, rather than merely a characteristic needing to be dealt with. While existing work reveals the importance of roughness, the field is still rather nascent and therefore this review highlights both challenges and opportunities for future research.
