摘要 ：
Porous aromatic frameworks (PAFs), possessing a high specific surface area, inherent porosity, nanosized channels and diverse structure, exhibit extraordinary potential in various fields. Herein, PAF-56 membranes were in situ fabricated on modified polyvinylidene fluoride (PVDF) membranes by a mild and facile refluxing method (62 degrees C) and applied in nanofiltration. The influence of reaction time, reactant concentrations and catalyst concentration on the PAF-56/PVDF membranes were explored. The PAF-56/PVDF membranes showed a remarkable rejection (>95.08 %) and permeability (>40 L m(-2)h(-1) bar(-1)) for dyes (Mw > 319) solutions. The membrane also exhibited excellent reusability and chemical stability, indicating great potential for actual separations.

摘要 ：
Acetic acid, as one of the top 50 important chemicals, has been broadly applied for production of cellulose acetate, polyvinyl acetate, as well as synthetic fibers and fabrics, and so on. However, the acetic acid production always involves in water which should be removed. Thus, energy-efficient and environmental-friendly dehydration of acetic acid is highly required in current chemical industry. In this study, we proposed a 'hard-crosslinking-soft' strategy to construct a kind of organic-inorganic hybrid membrane by doping aminated silica (SiO2-NH2) nanoparticles into the polyelectrolyte complex (PEC) membrane for dehydration of acetic acid. The addition of SiO2-NH2 nanoparticles plays two roles: one is as the 'hard' part to overcome the over-swelling issue of 'soft' PEC membrane; another is creation of more free volume for water passing through. As a result, the proposed hybrid membrane could simultaneously augment the permeability and selectivity of the pervaporation membrane, breaking the notorious 'trade-off' restriction of separation membranes. The preparation parameters and operation condition on the performance of the membrane were detailed studied. The optimized membrane offers a flux of 1225 g/m2h and a separation factor of 1442 in dehydration of 10 wt% water/acetic acid mixtures at 50 degrees C, with pervaporation separation index of 1.77 x 106 g/m2h, among the top-tier separation performance. Besides, the prepared membrane could stably work for 144 h due to the chemical crosslinking by glyoxal, promising for the practical application for acetic acid dehydration.

摘要 ：
In this study, a facile strategy for in situ growth of covalent triazine frameworks (CTFs) membrane on alpha-Al2O3 substrate was presented. An intact CTFs based composite membrane was obtained in a solvothermal growth process. The structure and property of the CTFs composite membranes were investigated. The results indicated that CTFs could grow in the pores of the alpha-Al2O3 substrate to modify the transport channel. Due to the sieving effect of the CTFs aperture, the prepared CTFs composite membrane exhibited superior rejection for different types of dyes (>97%) with extremely low rejection for salts (<20%). Moreover, the CTFs composite membrane had a high permeability (448 L m(-2)h(-1) MPa-1) and good stability for dye desalination. This approach demonstrated the great potential of CTFs membranes for dye/salt separation.

摘要 ：
Functional membranes generally wear out when applying in harsh conditions such as a strong acidic environment. In this work, high acid-resistance, long-lasting, and low-cost functional membranes are prepared from engineered hydrogen-bonding and pH-responsive supramolecular nanoparticle materials. As a proof of concept, the prepared membranes for dehydration of alcohols are utilized. The synthesized membranes have achieved a separation factor of 3000 when changing the feed solution pH from 7 to 1. No previous reports have demonstrated such unprecedentedly high-record separation performance (pervaporation separation index is around 1.1 x 10(7) g m(-2) h(-1)). More importantly, the engineered smart membrane possesses fast self-repairing ability (48 h) that is inherited from the dynamic hydrogen bonds between the hydroxyl groups of polyacrylic acid and carbonyl groups of polyvinylpyrrolidone. To this end, the designed supramolecular materials offer the membrane community a new material type for preparing high acid resistance and long-lasting membranes for harsh environmental cleaning applications.

摘要 ：
Molybdenum disulfide (MoS2) is widely used in membrane separation because of its outstanding chemical and structural stability. In this study, MoS2 nanosheets were in-situ grown on a tubular ceramic substrate through one-step hydrothermal synthesis with the graphene quantum dots (GQDs) incorporated in the precursor solution. The growth of the MoS2 nanosheets was inhibited due to the combination with GQDs through the Mo-O bond. Therefore, the number of transport channels in the MoS2/GQDs composite membrane were increased to improve the permeability. The results indicated that the MoS2/GQDs composite membrane have excellent permeances for both the aqueous solution and organic solvent. Moreover, the MoS2/GQDs composite membrane can be continuously operated in cross-flow filtration device for 100 h because the in-situ hydrothermal method has greatly improved the stability of membrane. The results indicated that the MoS2/GQDs composite membrane exhibits great potential in nanofiltration.

摘要 ：
Relative humidity (RH) is broadly involved in various areas, including industry, agriculture, medical engineering, as well as environments. Thus, development of a high-performance, low-energy consumption, flexible, and miniaturized RH sensing device is quite essential to meet the modern requirements. However, it is still a grand challenge to endow a RH sensor with all the above strengths. Herein, according to the electrical double layer mechanism, a RH-responsive poly (acrylic acid) is employed as a sensing layer and simultaneously a dielectric layer for fabrication of flexible organic thin-film transistor (OTFT) RH sensors, which could remarkably reduce the driven voltage of the OTFT device to 2 V. The sensitivity of such-designed sensors can be manipulated by tuning the driven voltage. Notably, all the fabricated OTFT sensing devices show reversibly linear response to RH and a fast response of around 4 s. Due to the solution-processing abilities and flexibility of the OTFT device, it can be miniaturized and integrated into multiple functional devices, e.g., soft medical devices.

摘要 ：
Nanofluidics derived from low-dimensional nanosheets and protein nanochannels are crucial for advanced catalysis, sensing, and separation. However, polymer nanofluidics is halted by complicated preparation and miniaturized sizes. This work reports the bottom-up synthesis of modular nanofluidics by confined growth of ultrathin metal-organic frameworks (MOFs) in a polymer membrane consisting of zwitterionic dopamine nanoparticles (ZNPs). The confined growth of the MOFs on the ZNPs reduces the chain entanglement between the ZNPs, leading to stiff interfacial channels enhancing the nanofluidic transport of water molecules through the membrane. As such, the water permeability and solute selectivity of MOF@ZNPM are one magnitude improved, leading to a record-high performance among all polymer nanofiltration membranes. Both the experimental work and the molecular dynamics simulations confirm that the water transport is shifted from high-friction-resistance conventional viscous flow to ultrafast nanofluidic flow as a result of rigid and continuous nanochannels in MOF@ZNPM.

摘要 ：
Graphene oxide (GO) has been considered as a promising material to develop advanced nanofiltration membranes to resolve the current worldwide water scarcity issue, benefiting from its extraordinary physicochemical properties. However, loose-GO-nanosheet-stacking rendered membrane compaction during operation significantly harms the mass transfer of GO membranes. Here, we proposed an ice-crystal templating approach to simultaneously tailor the two mass transfer channels of GO membranes, i.e., nanochannels originated from the interlayer spacing and microporous defects arising from poorly stacking of nanosheets. The tunability of the ice-crystal templating strategy was verified by low-field nuclear magnetic resonance (LF-NMR) coupled with X-ray diffraction patterns technique. The result demonstrated that the interlayer spacing can be precisely tuned from 7.5 to 9.3 A while the volume of microporous defects can be adjusted from 2.9% to 24.6%. Thus, the optimized GO membrane (M2) was utilized for desalination of dye/NaCl mixtures and accomplished a high separation performance, for example, high water permeability of similar to 22.6 LMH/bar (10-fold enhancement compared with traditional GO membranes), 100% rejection to EB dyes, 19% rejection to NaCl, and long-term running stability (180 h). Therefore, the innovative ice-crystal templating fabrication techniques opens the door for the design of high-efficiency 2D material-based membranes. (C) 2021 Elsevier Ltd. All rights reserved.

摘要 ：
Excessive CO2 emissions arising from fossil energy utilization pose severe threats to the environment, climate, and biological species. To this end, high-efficiency separation membranes have been developed to mitigate emerging challenges. Bisphenol A ethoxylate diacrylate (BPA) and poly(ethylene glycol) methyl ether acrylate (PEGMEA) were UV-cross-linked in the presence of low molecular weight poly(ethylene glycol) dimethyl ether (PEGDME) to prepare high-performance CO2 capture membranes in a green way. During the entire membrane fabrication process, no additional solvent was involved and no waste of membrane materials occurred, resulting in a green process. The such-prepared membrane presents an outstanding CO2 permeability of 4883 Barrer, a new record for poly(ethylene oxide) membranes, with a high CO2/N-2 ideal selectivity of 43 due to the cooperative contribution of BPA and PEGDME. The unprecedented separation performance of our manufactured membrane is even higher than that of the 2019 CO2/N-2 upper bound. Considering the rapid, cost-effective, and green fabrication process, our membrane potentially offers a dramatic advantage in alleviating the current greenhouse gas issue and shows great promise for practical applications.

摘要 ：
The robustness of carbon nanomaterials and their potential for ultrahigh permeability has drawn substantial interest for separation processes. However, graphene oxide membranes (GOms) have demonstrated limited viability due to instabilities in their microstructure that lead to failure under cross-flow conditions and applied hydraulic pressure. Here we present a highly stable and ultrapermeable zeolitic imidazolate framework-8 (ZIF-8)-nanocrystal-hybridized GOm that is prepared by ice templating and subsequent in situ crystallization of ZIF-8 at the nanosheet edges. The selective growth of ZIF-8 in the microporous defects enlarges the interlayer spacings while also imparting mechanical integrity to the laminate framework, thus producing a stable microstructure capable of maintaining a water permeability of 60 l m-2 h-1 bar-1 (30-fold higher than GOm) for 180 h. Furthermore, the mitigation of microporous defects via ZIF-8 growth increased the permselectivity of methyl blue molecules sixfold. Low-field nuclear magnetic resonance was employed to characterize the porous structure of our membranes and confirm the tailored growth of ZIF-8. Our technique for tuning the membrane microstructure opens opportunities for developing next-generation nanofiltration membranes.
