Gas transmission schematic of MMMs with high MOF loading via (A) traditional mixing method and (B) our symbiosis-inspired method, (C) permeability, (D) selectivity of 0.1-ZIF-7/PIM-1 and 0.1-ZIF-67/PIM-1, and (E) selectivity versus permeability for CO₂/N₂, where gas separation performance of the MMMs prepared in this work (stars), primary common polymeric membranes (hollow circles), and various MOF-based MMMs from literature (solid circles) are plotted against the Robeson plot of 2008 (13). A fully detailed comparison of the data in this plot is in SI Appendix, Table S6.
