(85a) Membrane Materials Under Complex Conditions

Membrane-based separations can provide an attractive alternative to other separation processes because of their modularity and compact size. However, literature data rarely matches performance under realistic conditions. This presentation will discuss current challenges related to gas-separation membranes, including stability to strongly interacting penetrants and the role of gas mixtures on membrane performance. The topics will focus on microporous membrane materials, including polymers of intrinsic microporosity (PIMs), catalytic arene-norbornene annulation (CANAL) polymers, and metal–organic frameworks (MOFs). Studies will demonstrate opportunities to leverage polymer and MOF structure and chemistry to suppress plasticization effects and to leverage competitive sorption, enabling material property sets measured under complex mixtures that can actually surpass those of property sets predicted from simple pure-gas experiments.
