Abstract
Printing technology has been received considerable attentions in history, and these days. These days, printing technology has been developed for smaller, more complicated, and more flexible structures, such as 3D printing, stretchable and/or transparent electronic device, rollable display, and so on. However, to obtain a uniform coating or to control a coating pattern is still far from complete. Hydrodynamic effects are predominant because solid materials should be transferred by liquid. In this seminar, we will talk about how we can achieve a uniform coating result or control a coating pattern when we use soft matters. The examples include coffee-ring-less QD-LED polygonal patterns, liquid metal coating, and drying of some other complex fluids as well. These problems characterize my approach of using optical measurement techniques to explore new questions in multiphase flows and physicochemical hydrodynamics.
