“…Nanosheets such as WS 2 or BN can be incorporated into polymer phase to form mixed‐matrix membranes with gas permeability and/or selectivity. The introduction of 10 % WS 2 into fluorinated poly(phenylene oxide) (FPPO) improved CO 2 permeability, CO 2 /N 2 selectivity, and CO 2 /CH 4 selectivity by 216 %, 148 %, and 137 %, respectively, because WS 2 provided transport channels for gas molecules . Similarly, introduction of functionalized BN nanosheets (1 wt %) into thermally rearranged polymers increased H 2 /CH 4 selectivity from 24.1 to 275 …”

Two‐dimensional nanosheets have shown great potential for separation applications because of their exceptional molecular transport properties. Nanosheet materials such as graphene oxides, metal–organic frameworks, and covalent organic frameworks display unique, precise, and fast molecular transport through nanopores and/or nanochannels. However, the dimensional instability of nanosheets in harsh environments diminishes the membrane performance and hinders their long‐term operation in various applications such as gas separation, water desalination, and ion separation. Recent progress in nanosheet membranes has included modification by crosslinking and functionalization that has improved the stability of the membranes, their separation functionality, and the scalability of membrane formation while the membranes’ excellent molecular transport properties are retained. These improvements have enhanced the potential of nanosheet membranes in practical applications such as separation processes.

“…Nanosheets of TMDs such as WS 2 have been explored as membrane materials and can also play a role as nanofillers for TFN membranes. 126,127 Other emerging nanosheets such as MXene and COF are at a very primitive stage in research and development in terms of being used as nanofillers for TFN membranes. Their impact on the PA layer properties and membrane performance must be comprehensively evaluated and benchmarked against commercial membranes.…”
