Title: Dynamic Polymers for Future Technologies
Unlike manmade polymers, macromolecules in biological systems undergo constant dissociation, association, and reconfigurations to perform living functions. By incorporating dynamic chemistry, such as reversible covalent bonds or supramolecular interactions, into polymer networks, novel functionalities similar to biological systems can be achieved. Such materials are called dynamic polymers. One property of interest is self-healing. Driven by the opportunity to develop life-like materials and sustainable technologies, self-healing synthetic polymers have attracted much interest in the last two decades. I will discuss our recent approaches in utilizing inexpensive commodity monomers to develop self-healable polymers, and the underlying chemical and physical principles. Mechanical damages such as scratches can be healed with minimum human intervention. I will also discuss future directions for dynamic polymers. We are interested in exploring new areas in mechano-responsiveness, upcycling, next-generation self-healing, and reversible networks via bottom-up macromolecular synthesis and precise structural control.
Dr. Ying Yang received her B.S. in Chemistry from Nankai University in China in 2010 and her Ph.D. in Materials Science and Engineering from Clemson University in 2016 working with Prof. Marek W. Urban on self-healing polymers. After completing a postdoctoral research position at Clemson, she joined the Chemistry faculty at University of Nevada, Reno this year. Dr. Yang’s research interests are in studying polymers’ responses to external force and deformations, synthesis of mechano-responsive polymers, and development of sustainable polymers.
