제목 Interactions, Assemblies, and Applications of Colloid Particles at Fluid-Fluid Interfaces
초록 The behavior of colloidal particles at two-dimensional fluid-fluid interfaces is of considerable interest as a building block for bottom-up approaches with applications in stabilizers in emulsion systems (i.e. detergents, paints, inks, and cosmetic) and flocculants or coagulants in separation processes (i.e. oil recovery/oil separation, waste water treatment). To quantitatively control the physical properties and the corresponding macroscopic behaviors (rheology and phase behaviors) of such bulk suspensions, it is imperative to understand the behaviors between individual constituents in a microscopic scale. Here, I present the configurations, interactions and assemblies of various types of colloidal particles at fluid-fluid interfaces. I also show the interconnection between finding the nature of material properties on a microscopic scale and controlling the macroscopic bulk behaviors. Based on these fundamental understanding of interfacial phenomena of colloidal particles, I introduce a novel practical application, which is the phase-transfer catalysis in microemulsion reactors.
