Thermally Rearranged Mixed Matrix Membranes (TR-MMM) for Permeability Enhancement and Mechanical Toughness
Abstract
Thermally Rearranged (TR) polymers and Mixed Matrix Membranes (MMMs) are two effective approaches used to advance the performance of gas separation membranes. The TR approach can improve membrane performances by the inclusion of thermally activated groups that form hourglass-shaped cavities at high temperature, resulting in unusually high gas separation performance. On the other hand, MMMs’ inclusion of nanoparticles with engineered pore volume, window size and/or surface chemistry can add fast and selective pathways for enhanced membrane permselectivity. While both methods readily enhance permeation, researchers must also focus on the other factors affecting the application of advanced membrane materials, namely aging, plasticization, and mechanical stability. In this study, we explored the effects of combining these two approaches by adding ultra-porous and highly thermostable PAF-1 nanoparticles into the TR-able polymer, 6FDA-HAB5DAM5 (DAM). Gas separation performances of TR-MMMs were evaluated particularly by comparison with the pure polymer and another TR-MMM bearing an already thermally-treated PAF-1 additive (cPAF). By combining thermal rearrangement process with PAF-1, the resulting TR-MMM membrane demonstrated a 55-fold increase in CO2 gas permeability (37 for H2), without sacrificing gas selectivities or catastrophic film embrittlement observed in the case of pure TR film.
