Ion and solvent permeability of polymer networks and gels are critical to a variety membrane applications ranging from water desalination to batteries to medical devices. The polymer chemistry and structure of these materials are critical to defining permeability, yet the specific relationships are not well established. Model polymer networks with well-defined chemistry and structure are needed to carry out quantitative measurements to establish design principles for membrane materials. We are interested in polymer networks with defined molecular architecture (functionality and molecular mass distribution), as well as polymer chemistry that will solubilize water and monovalent ions (i.e., lithium, sodium ions). Experimental methods for this opportunity include gel-permeation chromatography, small angle neutron scattering, and nuclear magnetic resonance.
