    The Evans group is interested in probing the physics of polymer networks with the incorporation of dynamic covalent bonds and added salts. We are pursuing a fundamental understanding of polymer properties such as energy dissipation, self-healing, crystallization, and transport of small molecules through the network. The group combines molecular design of precise polymers with advanced characterization approaches to determine structure-property relationships in dynamic, ionic networks. Application of networks in the group include supercapacitors, actuators, membranes, batteries, and shockwave dissipating polymers which are informed by our fundamental investigations.
