Abstract/Summary:
This dissertation examines the mesophase formation and rheological properties of evaporation-induced self-assembly (EISA) fluids both at equilibrium state and under processing conditions, and presents an evolution equation for the thin films derived from EISA fluids during dip-coating. This equation reflects the evaporation-induced Theology change and predicts the steady-state film thickness and meniscus shape which significantly enhances the manipulation of mesophase materials synthesis. Also, this dissertation presents a composite optical waveguide design that makes use of EISA fluid produced thin film which gives aid to the submicron optical fiber/microfluidic device integration.
