Membrane-based gas separations

The development of polymeric materials for commercial membrane-based gas separations has stagnated for a quarter of a century. This project is developing an approach to make processable polymers featuring a flexible backbone connected to tunable, rigid, pore-generating side chains. With record stabilities under aggressive feeds, these polymers are a promising platform of materials to replace current gas-separation membranes.


Technology from this project spun out into a company, Osmoses.
