“…1,2 Among the various separation technologies, membrane separation offers several advantages, including environmental friendliness, simple fabrication, trouble-free application, low capital cost, low energy consumption, well-space utility, and excellent thermal suitability. 3 However, polymeric membranes have some shortcomings to meet industrialization standards due to the well-known "trade-off" between permeability and selectivity. 4 Mixed matrix membranes (MMMs) are designed to exceed Robeson's upper bounds to get around the tradeoff between permeability and selectivity.…”
