In this study, Tröger’s Base (TB) chemistry is exploited to introduce tunable microporosity in commercially available polyimide membranes. Considering that TB is a rigid, V-shaped and bridged alicyclic amine, there have been notable reports on accessing feasibility in TB for gas separation membrane applications. However, this presentation shows a different but much viable preparation approach in comparison to the already reported ones. This approach only requires commercially available monomers with two preparation steps, thus it can accommodate scalable and practical productions. Five different kinds of homopolymers and six copolymers were explored to demonstrate structure-property-performance relationships and to evaluate practical applicability towards industrial level.
