Membranes have been considered as promising alternatives for natural gas sweetening. Mixed matrix membranes (MMMs) possess superior separation performance and the potential to combine varieties of polymers filler materials. In current work, MMMs fabricated via employing Tröger's base (TB) polymer zeolites with three different morphologies. Simultaneously, CO2/CH4 H2/CH4 performances obtained were comprehensively investigated. It is found out that presence MFI-type significantly improved permeability, but selectivity was somehow reduced. Among nanofillers, nanosheet zeolite-based presented highest permeability; 20 wt % zeolites, both CO2 H2 permeabilities increased 348.6 441.5 Barrer, which by 522.0 256.2%, respectively. addition, SEM, XRD, FTIR, TGA also employed characterize MMMs.

Abstract Porous aromatic frameworks (PAFs) show promising potential in anionic conduction due to their high stability and customizable functionality. However, the insolubility of most PAFs presents a significant challenge processing into membranes subsequent applications. In this study, continuous PAF with adjustable thickness were successfully created using liquid‐solid interfacial polymerization. The rigid backbone stable C−C coupling endow membrane superior chemical dimensional stabilities over conventional polymer membranes. Different quaternary ammonium functionalities anchored through flexible alkyl chains tunable length. optimal exhibited an OH − conductivity 356.6 mS ⋅ cm −1 at 80 °C 98 % relative humidity. Additionally, outstanding alkaline stability, retaining 95 its after 1000 hours 1 M NaOH. To best our knowledge, is first application materials anion exchange membranes, achieving highest exceptional chemical/dimensional stability. This work provides possibility for conductive
