By supporting on porous substrates, Pd layer thickness can be reduced to several micrometers, thus improving the H2 permeance by several orders of magnitude. However, the supported thin Pd membranes are concomitant with pinhole formation due to either fabrication (e.g., electroless-plating) or thermal treatment, which exist as a remarkable challenge for its widespread applications. This study presents a novel and facile approach for self-repair of Pd membrane defects by immersing the stainless-steel supported Pd membranes in PdCl2 solution. Three membranes were deliberately selected with a low selectivity of 152–1687 (400 °C, 0.1Mpa), for which disproportionation reactions between Pd2+ and Fe/Cr/Ni at the defect sites spontaneously occur leading to the formation of Pd particles at the exact point of defects. This self-repair process can be enhanced when applying a high pressure of 30–50 bar in the PdCl2 solution for 30 min, by overcoming the capillary resistance and penetrating through the pinholes. Interestingly, densely distributed hillocks were observed on the membrane surface probably due to reduction of PdCl2 under following H2 treatment, thus increasing the H2 permeance with a higher effective surface area. The H2/N2 selectivity can be improved by more than one order of magnitude (in the best case from 1687 to 8768) and a long-term stability test of 300 h was achieved for the repaired membranes, corroborating the application potential of this approach.</div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"3 ","pages":"Article 100077"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823423000180/pdfft?md5=8607d201574e4e495d7bb99e187e5286&pid=1-s2.0-S2772823423000180-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138466487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparing to commercially available polyimide ISA membranes and polyamide TFC membranes, multiple categories of emerging polymer materials result in membranes with much improved permselectivity for highly efficient molecular separation.

Here, thin film composite (TFC) hollow fiber (HF) membrane with an in-situ-crosslinked ultrathin CS selective layer is developed via multiple supramolecular interaction-crosslinking strategy for efficient water/ethanol separation via pervaporation. With Fe3+-phytic acid (PhA) complex pre-deposited on the substrate, the subsequently introduced CS selective layer is in-situ crosslinked via multiple supramolecular interactions, including coordination, electrostatic, and hydrogen bonding interactions. By varying the cycle number of Fe3+/PhA assembly and the species of employed organophosphorus acid, the anti-swelling properties of the resultant TFC CS membrane is enhanced and the separation performance is maximized. The optimal TFC-CS-Fe2PhA2 membrane with two cycles of Fe3+/PhA assembly has a selective layer thickness of 60 nm and a corresponding ultrahigh flux of 2.87 kg/m2 h, coupled with a permeate water concentration of 99.5 wt% and good long-term stability for the dehydration of 85 wt% ethanol aqueous solution at 50 °C.

We present an in-depth study to identify and unify the effects of solvent parameters on solute rejection. For this purpose, we measured the rejection of 407 solutes in 11 common and green solvents using a polyimide membrane in a medium-throughput cross-flow nanofiltration system. Based on the large dataset, we experimentally verify that permeance and electronic effects of the solvent structure (Hildebrand parameters, electrotopological descriptors, and LogP) have strong impact on the average solute rejection. We furthermore identify the most important solvent parameters affecting solute rejection. Our dataset was used to build and test a graph neural network to predict the rejection of solutes. The results were rigorously tested against both internal and literature data, and demonstrated good generalization and robustness. Our model showed 0.124 (86.4% R2) and 0.123 (71.4 R2) root mean squared error for the internal and literature test sets, respectively.

However, PDA-based nanofiltration membranes are limited by the long preparation time and moderate flux. This work modulated PDA deposition processes with a spiro-piperazine (SPIP) molecule containing two secondary amine groups and a quaternary ammonium salt. The SPIP could be covalently inserted into PDA coating structures via Michael addition reaction to accelerate the deposition process of PDA and reduce its aggregation. In addition, the rigid and spiro configuration of SPIP molecules provides higher fractional free volume and leads to looser and more uniform structures in the PDA coating. As such, water permeance of PDA/SPIP membranes is 73 L m−2 h−1 bar−1, 4.6 times improved compared with PDA control membranes, while the dye rejection (>99% for Congo red) is maintained high.

This system mainly depends on the gas-blood exchange membrane, the quality of which impacts the oxygenation performance. Currently, the most widely used gas-blood exchange membrane is made of poly(4-methyl-1-pentene) (PMP) hollow fibers. However, plasma leakage often occurs during clinical applications, which decreases the oxygenation performance and the service life and may endanger the patient's life in serious cases. In this work, Hyflon AD/PMP hollow fiber composite membranes were prepared by coating Hyflon AD on the surfaces of PMP hollow fibers to form ultra-thin, dense layers. Compared the plasma leakage time of the composite membrane with that of the pristine PMP membrane, the Hyflon AD60 layer showed great improvement in anti-leakage performance. The Hyflon AD60/PMP hollow fiber composite membrane possessed lower platelet adhesion and protein adhesion than that of the PMP membrane, indicating better blood compatibility of the Hyflon AD60 membrane. Cytotoxicity experiments were conducted to further confirm the biosafety of Hyflon AD60 as a blood contact medical membrane material. Gas permeance and oxygenation performance of the Hyflon AD60/PMP hollow fiber composite membrane were tested to ensure gas exchange efficiency during the gas separation process.
