The dynamic interaction between liquid drops and a solid surface is greatly influenced by its microscopic structure, including its topography and material composition. While phenomena such as capillarity and hydrophobicity have been studied for many years, recent research has produced remarkable new insights in this field. Here, we review the physical principles that produce movement of drops, develop models for their behavior, discuss the design and fabrication of micro-structured surfaces, and demonstrate several applications including self-cleaning surfaces and a microfluidic platform for parallel processing of liquid samples. The presentation will feature highlights from the most recent and pending publications.
液滴与固体表面之间的动态相互作用在很大程度上受到其微观结构（包括其形貌和材料组成）的影响。 尽管对毛细现象和疏水性等现象进行了多年研究，最近，我们的研究在该领域产生了令人瞩目的新见解。我们回顾了产生液滴运动的原理，开发了其行为模型，讨论了微结构表面的设计和制造，并演示了包括自清洁表面和用于并行处理液体样品的微流体平台在内的几种应用。 本次报告将重点介绍我们最新的工作进展。
