Abstract: A major challenge in the development of anion exchange membranes for fuel cells is the design and synthesis of highly stable (chemically and mechanically) and conducting membranes. Membranes that can endure highly alkaline environments while rapidly transporting hydroxides are desired. A design for using cross-linked polymer membranes is disclosed to produce ionic highways along charge delocalized pyrazolium and homoconjugated triptycenes. The ionic highway membranes show improved performance in key parameters. Specifically, a conductivity of 111.6 mS cm?1 at 80° C. was obtained with a low 7.9% water uptake and 0.91 mmol g?1 ion exchange capacity. In contrast to existing materials, these systems have higher conductivities at reduced hydration and ionic exchange capacities, emphasizing the role of the highway. The membranes retain more than 75% of initial conductivity after 30 days of alkaline stability test.

Abstract: Membranes comprising graphene oxide sheets and associated filter media and methods are provided. In some embodiments, a membrane may comprise graphene oxide sheets that have undergone one or more chemical treatments. The chemical treatment(s) may impart beneficial properties to the membrane, such as a relatively small d-spacing, compatibility with a broad range of environments, physical stability, and charge neutrality. For example, the graphene oxide sheets may undergo one or more chemical treatments that form chemical linkages between at least a portion of the graphene oxide sheets in the membrane. Such chemical linkages may impart a small d-spacing, broad compatibility, and/or allow relatively thick membranes to be formed. In certain embodiments, the graphene oxide sheets may undergo one or more chemical treatment that imparts relative charge neutrality to the membrane by altering the ionizability of certain functional groups.
