The Ku research group, PCFL (Polymers & Complex Fluids Laboratory) at UNIST is interested in design, synthesis, and engineering of advanced soft matter. The aim of the research is to understand the physical and chemical behavior of soft matter based on polymer science and colloid / interface engineering. We are currently interested in the following topics:* Polymer Chemistry and Physics: (1) Engineering of polymer architecture and self-assembly behavior, (2) Development of functional polymer nano composite materials for various applications (cosmetics, displays, batteries, bio-medical fields) * Colloid Mechanics: (1) Assembly and patterning of multiple colloids, (2) Shape and movement control of complex colloids * Soft Robotics: (1) Design of smart colloid units with liquid crystals, liquid crystalline elastomer, and photonic polymers, (2) Manufacturing of colloid actuator driven by external stimuli
