Controllable ion transport through nanochannels is crucial for biological and artificial membrane systems. Covalent organic frameworks (COFs) with regular tunable are emerging as an ideal material platform to develop synthetic membranes transport. However, exclusion by COF remains challenging because most materials have large-sized leading nonselective of small ions. Here we ionic (iCOFMs) control charged framework nanochannels, the interior surfaces which covered arrayed sulfonate groups render superior charge density. The overlap electrical double layer in blocks entry co-ions, narrows their passageways, concomitantly restrains permeation counterions via balance. These highly within iCOFM enable while maintaining intrinsically high water permeability. Our results reveal possibilities controllable based on purification, separation, sensing, energy conversion.

The successful implementation of thin-film composite membranes (TFCM) for challenging solute-solute separations in the pharmaceutical industry requires a fine control over microstructure (size, distribution, and connectivity free-volume elements) thickness selective layer. For example, desalinating antibiotic streams highly interconnected elements right size to block antibiotics but allow passage salt ions water. Here, we introduce stevioside, plant-derived contorted glycoside, as promising aqueous phase monomer optimizing TFCM made via interfacial polymerization. low diffusion rate moderate reactivity together with its nonplanar distorted conformation, produced thin layers an ideal microporosity desalination. optimized 18-nm membrane exhibited unprecedented combination high water permeance (81.2 liter m-2 hour-1 bar-1), desalination efficiency (NaCl/tetracycline separation factor 11.4), antifouling performance, chlorine resistance.

Membrane-based water reuse through reverse osmosis (RO) and nanofiltration (NF) faces a critical challenge from organic micropollutants (OMPs). Conventional polyamide RO NF membranes often lack adequate selectivity to achieve sufficient removal of toxic harmful OMPs in water. Tailoring membrane chemistry structure allow highly selective has risen as an important topic membrane-based reuse. However, literature gap remains be addressed: how design for more OMPs. In this review, we critically analyzed the roles on highlighted opportunities strategies toward context Specifically, statistically rejection by conventional illustrate their drawbacks removal, followed discussion underlying fundamental mechanisms. Corresponding tailor properties improving against OMPs, including surface modification, nanoarchitecture construction, deployment alternative materials, were systematically assessed terms permeance, rejection, water–OMPs selectivity. end, discussed potential challenges various scale-up real applications.

Highly permeable polyamide (PA) membrane capable of precise ionic sieving can be utilized for many energy-efficient chemical separations. To fulfill this target, it is crucial to innovate membrane-forming process induce a narrow pore-size distribution. Herein, we report an anhydrous interfacial polymerization (AIP) at solid-liquid interface where the amine layer sublimated in direct contact with alkane containing acyl chlorides. In such heterophase interface, water-caused side reactions are eliminated, and amines compact arrangement enable intensive orderly IP reaction, leading unique PA accuracy 0.5 Å. The AIP-PA demonstrates excellent separation selectivities monovalent divalent cations as Mg2+/Li+ (78.3) anions Cl-/SO42- (29.2) together high water flux up 13.6 L m-2 h-1 bar-1.
