Polymer Zwitterions as Adhesive Surfactants

Congratulations to undergraduate researcher Annelise (Annie) Busch, who will present her joint summer research with the Kroo and Emrick groups on adhesive polymer surfactants at AIChE. The work examines how salt concentration changes the rheology of adhesive droplet networks and the transition between surfactant-like interfaces and elastic films.
