Abstract

Solid-liquid interfaces are ubiquitous in nature and technology, ranging from droplets on plant leaves and animal skins to blood interacting with biomedical devices to vapors condensing on a condenser. The past two decades have seen significant advances in understanding and tailoring solid-liquid interfaces. In this talk, I will discuss the fundamental physical and chemical principles behind tailoring solid-liquid interfaces. Building on these fundamental principles, I will present examples of superomniphobic surfaces, which are extremely repellent to virtually all liquids. Then, I will present a few examples of stimuli-responsive surfaces with applications in protective clothing and liquidhandling robots. Next, I will discuss the design of novel and counter-intuitive surfaces with applications in anti-thrombotic biomedical implants. Finally, I will wrap up with the design of surfaces for enhanced condensation and anti-icing .
