Thermodynamics of Supramolecular Polymers

Polymers that form reversible linkages are difficult to describe with typical theoretical approaches. The central challenge is enumerating all of the possible reaction products. Coherent states (CS) polymer field theory sidesteps this main challenge; however, the CS approach is relatively underdeveloped. My work extends CS field theories to a broader set of polymer systems, including those with multiple components and reactions.

Ionic Compatibilzation of Polymer Blends

Chemically dissimilar polymers tend not to mix, which limits the extent of plastic recycling. By functionalizing existing polymers with acid/base moeities, one can promote mixing through the favorable electrostatic interaciton. The combination of electrostatics and the reversible nature of the proton-transfer reaction requires novel polymer field theories to guide experimental design. My work contributes toward navigating the vast design space for functionalization and developing theory to predict the phase behavior of reversibly bonding polymer blends.
