Our research is focused on rationally designed, precisely synthesized responsive and functional polymers for advancing fundamental understanding and targeting potential applications. Current research interests include: (i) macromolecular brush materials (hairy/brush particles and bottlebrush polymers), (ii) stimuli-responsive nonionic, ionic, and zwitterionic polymers, (iii) polymer materials for removal of toxic persistent oxyanions from water for water treatment, and (iv) chiral ferroelectric liquid crystalline polymers. State-of-the-art polymerization methods and organic synthesis tools are used to prepare these polymeric materials, and various characterization techniques are applied to determine their structures, behaviors, and properties. Our research involves polymer science, materials chemistry, surface and colloidal science, and environmental chemistry.
