Effect of pore size distribution on the desalination performance of the selective layer of nanoporous atomically-thin membranes

Metal/covalent–organic framework based thin film nanocomposite membranes for advanced separations

“…These demonstrate that network pores in PA membranes have a wide distribution and are not well interconnected, leading to a trade-off relation between water permeability and solute–solute selectivity. 90 Therefore, developing fit-for-purpose TFN membranes that feature narrowly distributed and interconnected pore channels is pivotal yet challenging to boost their filtration performance.…”

Effect of Membrane Permeance and System Parameters on the Removal of Protein-Bound Uremic Toxins in Hemodialysis

“…The emergence of new membrane materials opens the possibility to surpass these limitations and achieve higher membrane permeance with better control of pore characteristics. For example, nanoporous atomically thin membranes (NATMs) made from graphene have been shown both experimentally and computationally to permit rapid solute diffusion while maintaining selectivity, with the selective layer being only 1-atom (< 0.4 nm) thick, and membrane fabrication using scalable methods has been demonstrated [ 4 , 7 , 8 , 19 , 20 , 12 ]. Single-layer graphene membranes can also withstand pressure differentials up to 100 bar if placed on the appropriate support structure, compared to typical transmembrane pressure (TMP) of < 300 mmHg (0.4 bar) [ 35 , 50 ].…”
