Symposium Technical Description

Polymers with dynamic bonds have shown great capability in adapting their environment and exhibiting unprecedented properties, such as high-toughness, self-healing and mechanochromism. In this emerging field, dynamic bonds, including reversible covalent bonds and non-covalent bonds (such as ionic bonds, hydrogen bonds, metal-ligand coordinations and hydrophobic interactions), have been utilized to program macroscopic responses of polymers by regulating their molecular architectures. From a fundamental perspective, development of predictive models that connect the macroscopic mechanical behaviors of these polymers to the corresponding molecular mechanisms is a challenging endeavor. The proposed symposium will address recent experimental, computational and theoretical advances in this burgeoning field. Topics of particular interest include: (a) Tough hydrogels and elastomers; (b) Self-healing polymers; (c) Mechanochemically responsive polymers; (d) Covalently adaptable polymers; (e) Photoresponsive polymers; and (f) Electromagnetically responsive polymers.
