Faced with growing demand for better healthcare, cleaner energy, more sustainable materials, innovations at the interface of organic and macromolecular chemistry are essential to bring forward green chemical solutions to the evolving challenges of our time. By introducing reversibility and dynamics, the synthetic macromolecules are benefited with better longevity, new properties, and advanced functions. The Liu Group is interested in learning the fundamental principles for a variety of dynamic phenomena in macromolecular sciences, designing methodologies for dynamic polymers, and discovering ways to dynamically control transformation and interactions of synthetic polymers.
