The Artificial Womb Technology (AWT) system is a piece of biomedical equipment that supports the in vitro development of extremely premature infants. The system draws fetal blood, oxygenates it, removes carbon dioxide (CO₂), and then delivers it back to the fetus. This prevents the fetus from switching to a pulmonary breathing pattern prematurely, which provides critical time for lung tissue development. Researchers have utilized extracorporeal membrane oxygenation (ECMO) technology to provide the fetus with oxygen. In this study, we developed a new method using artificial blood instead of maternal blood in a liquid-liquid dual-circulation. Additionally, since preterm infants require greater blood compatibility and the oxygenated membrane must have anticoagulant properties, the membrane was modified to enhance hemocompatibility and anticoagulant properties. PMP membranes were functionalized with polydopamine (PDA), after which (3-(methacrylamido) propyl) dimethyl (3-thiopropyl) ammonium hydroxide inner salt (SPP) and fondaparinux sodium were successively grafted. Protein adsorption reached 18.3 μg/cm² (64.3 % reduction), while hemolysis rate dropped to 0.19 % (85.4 % reduction). The results confirm that the functionalized modified membrane not only meets the blood compatibility requirements of the dual-circulation system but also accurately replicates the recurrent process of fetal-maternal gas exchange through its biomimetic design, providing key technical support for the clinical translation of the AWT system.

人工子宫技术（AWT）系统是一种支持极早产儿体外发育的生物医学设备。该系统抽取胎儿血液，为其充氧，去除二氧化碳，然后将其输送回胎儿体内。这可以防止胎儿过早地切换到肺呼吸模式，为肺组织发育提供关键时间。研究人员利用体外膜氧合（ECMO）技术为胎儿提供氧气。在这项研究中，我们开发了一种在液-液双循环中使用人工血液代替母体血液的新方法。此外，由于早产儿需要更高的血液相容性，而氧合膜必须具有抗凝血性能，因此对膜进行了修饰以增强血液相容性和抗凝血性能。用聚多巴胺（PDA）对PMP膜进行功能化处理，然后依次接枝（3-（甲基丙烯酰胺）丙基）二甲基（3-硫丙基）氢氧化铵内盐（SPP）和氟达哌啶钠。蛋白质吸附达到18.3 μg/cm2（降低64.3%），溶血率降至0.19%（降低85.4%）。结果证实，功能化修饰膜不仅满足了双循环系统的血液相容性要求，而且通过仿生设计准确复制了胎母气体交换的循环过程，为AWT系统的临床转译提供了关键技术支持。

Electrodialysis technology is widely deployed in the field of separation due to its simplicity of operation and sustainability, where ion-exchange membranes are the most critical components in this process. Traditional cation-exchange membranes are typically suitable for mild conditions and often suffer from issues such as poor stability and susceptibility. In this study, we design a novel cation-exchange membrane featuring a rigid backbone with sulfonic acid groups as side chains and fluorine-containing region. The resultant membrane exhibits high thermal stability, acid resistance, and oxidation resistance, without degradation of functional groups and decline in mechanical strength after treatment in 1 mol L⁻¹ HCl solution at 60 °C for over 1000 h. Moreover, its oxidation resistance in Fenton reagent at 80 °C surpasses that of commercial membranes. The Li⁺ recovery ratio from acidic leach liquors of lithium ores can reach ∼99.6 % via the electrodialysis process, demonstrating the membrane as a candidate for lithium extraction in aggressive industrial scenarios.

电渗析技术因其操作简单和可持续性而被广泛应用于分离领域，其中离子交换膜是该过程中最关键的部件。传统的阳离子交换膜通常适用于温和的条件，并且经常存在稳定性差和易感性等问题。在本研究中，我们设计了一种新型阳离子交换膜，该膜具有以磺酸基为侧链的刚性骨架和含氟区域。所得膜在60°C的1 mol L−1 HCl溶液中处理1000 h以上，具有较高的热稳定性、耐酸性和抗氧化性，没有官能团的降解和机械强度的下降。在Fenton试剂80℃下，其抗氧化性能优于商品膜。通过电渗析工艺，从锂矿的酸性浸出液中Li+的回收率可以达到~ 99.6%，这表明该膜在侵略性工业场景下是锂提取的候选膜。

A novel class of mixed-matrix membranes was synthesized through strategic integration of Polyether-block-amide (PEBAX) with Deca-dodecasil 3R (DD3R) zeolitic fillers, targeting efficiency-driven ethanol recovery in pervaporation separation systems. The DD3R molecular sieve was synthesized using adamantylamine (ADA) as a structure-directing agent and Sigma-1 seed crystals in a pure silicon precursor system. To improve compatibility with the polymer matrix, the DD3R particles were surface-modified with a silane coupling agent. Comprehensive characterization through Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectra (XPS), Water Contact Angle (WCA), X-ray diffraction (XRD), swelling degree tests, and mechanical properties confirmed the successful bonding of the silane coupling agent to both DD3R and PEBAX. The optimized membrane containing 0.75 wt% DD3R achieved a flux of 1152.06 g/m²h and a separation factor of 4.52 at 60°C with a 5 wt% ethanol feed concentration, representing a 115 % enhancement in flux and a 68 % increase in separation factor compared to the pristine PEBAX membrane. Additionally, the PEBAX/DD3R membrane displayed excellent long-term stability. This work provided a foundation for developing membranes with DD3R incorporated therein for a wide range of liquid or gas mixture separation processes.

通过将聚醚嵌段酰胺（PEBAX）与十-十二烷基3R （DD3R）沸石填料的策略整合，合成了一类新型混合基质膜，旨在提高渗透蒸发分离系统中乙醇的效率。在纯硅前驱体体系中，以金刚胺（ADA）为结构导向剂和Sigma-1种子晶体合成了DD3R分子筛。为了提高与聚合物基体的相容性，用硅烷偶联剂对DD3R颗粒进行了表面改性。通过傅里叶变换红外光谱（FTIR）、扫描电镜（SEM）、x射线光电子能谱（XPS）、水接触角（WCA）、x射线衍射（XRD）、溶胀度测试和力学性能的综合表征，证实了硅烷偶联剂与DD3R和PEBAX的成功结合。在60°C、乙醇浓度为5 wt%的条件下，优化后的含0.75 wt% DD3R的膜通量为1152.06 g/m2h，分离系数为4.52，与原始PEBAX膜相比，通量提高了115%，分离系数提高了68%。此外，PEBAX/DD3R膜表现出优异的长期稳定性。这项工作为开发用于各种液体或气体混合物分离工艺的含有DD3R的膜提供了基础。

Oil spills and the release of oily wastewater have caused serious damage to the environment and human health. Effective removal of oil spills and separation of oil/water mixtures have become a crucial step before they enter the environment and reveal their potentially harmful effects on aquatic ecology. In this context, herein, fibrous membranes based on sulfonated poly (ether-ether-ketone) (SPEEK) were produced and used for the adsorption of crude oils and their derivatives. PEEK was treated with H₂SO₄ at different times, and the concentrated solutions of the SPEEK were electrospun into bead-free nanofibers. The contact angle measurements with water and oils (i.e., crude oils, diesel, and gasoline) demonstrated the amphiphilic nature of the membranes. Depending on the crude oil sample used and the degree of sulfonation (DoS) of SPEEK, the crude oil sorption capacities ranged from 9 to 80 g g⁻¹, while the adsorption capacities for gasoline and diesel were measured as 3 and 13 g g⁻¹, respectively. As the DoS increased, the oil adsorption capacity of fibrous membranes declined due to the increased hydrophilicity of the membranes. Due to their amphiphilic nature, the SPEEK membranes could effectively remove even a thin layer of oil on seawater, a task that is challenging for most hydrophobic adsorbents. Fibrous SPEEK membranes could be employed as low-cost solutions for oil spill remediation and oil-in-water separation.

石油泄漏和含油废水的排放对环境和人类健康造成了严重损害。有效清除溢油和分离油水混合物已成为其进入环境并暴露其对水生生态的潜在有害影响之前的关键步骤。在此背景下，本文生产了基于磺化聚醚醚酮（SPEEK）的纤维膜，并用于吸附原油及其衍生物。用不同时间的H2SO4处理PEEK，将SPEEK浓缩液电纺成无珠纳米纤维。与水和油（即原油、柴油和汽油）的接触角测量证明了膜的两亲性。根据所使用的原油样品和SPEEK的磺化程度（DoS），原油的吸附量为9 ~ 80 g g−1，而汽油和柴油的吸附量分别为3和13 g g−1。随着DoS的增加，纤维膜的油吸附能力下降，这是由于膜的亲水性增加。由于SPEEK膜的两亲性，它可以有效地去除海水上一层薄薄的油，这对于大多数疏水吸附剂来说都是一个挑战。SPEEK纤维膜可以作为低成本的解决方案用于溢油修复和油水分离。

Cellulose-based separation membranes are promising for sustainable membrane technology due to their renewable raw materials and biodegradability. Their excellent resistance to fouling, minimal protein adsorption, and high biocompatibility render them effective in bio-separation applications. Nevertheless, the development of truly sustainable cellulose membranes for engineering purposes remains challenging. This review begins by outlining the raw cellulosic materials employed in membrane fabrication, followed by a systematic summary of the fabrication techniques for cellulose-based membranes derived from various raw materials, alongside their progress in bio-separation. The sustainability of cellulose-based separation membranes is assessed within a life cycle framework that considers raw materials, membrane fabrication, application scenarios and end-of life, with particular emphasis on key barriers to achieving engineering sustainability. Finally, this review proposes targeted optimization strategies to tackle these limitations, offering a clear roadmap for future research aimed at transforming cellulose-based membranes from promising laboratory innovations into robust, scalable engineering solutions.

This study presents an innovative method to accurately predict CO₂ permeability and the selectivity of CO₂/N₂, CO₂/CH₄, and CO₂/H₂ in mixed matrix membranes (MMMs) containing polymers and two-dimensional (2D) nanoparticles. A number of neural network models were used to examine the connection between six input variables (feed pressure, polymer type, filler content, 2D filler, additive type, and modification process) and two output variables (permeability and selectivity). The proposed method was tested on different neural network architectures using measurements like Mean Absolute Error (MAE) and Correlation Coefficient (R²). The neural network models were constructed with one, two, and three hidden layers, each containing a variation of neurons. These findings indicate the existence of a workable model that effectively mitigates bothunderfitting and overfitting occurrences. Another test on the suggested neural network model showed that the type of polymers, the amount of fillers, and the feed pressure had the most significant impact on gas permeability and selectivity. The proposed approach holds significant promise for predicting gas transport properties while minimizing the need for substantial time and financial resources.

该研究提出了一种创新的方法，可以准确预测含有聚合物和二维纳米颗粒的混合基质膜（MMMs）中的CO2渗透率和CO2/N2、CO2/CH4和CO2/H2的选择性。研究人员使用了许多神经网络模型来检验六个输入变量（进料压力、聚合物类型、填料含量、2D填料、添加剂类型和改性工艺）和两个输出变量（渗透率和选择性）之间的联系。采用平均绝对误差（MAE）和相关系数（R2）等测量方法在不同的神经网络结构上进行了测试。神经网络模型由一层、两层和三层隐藏层构建，每层隐藏层包含不同的神经元。这些发现表明，存在一种可行的模型，可以有效地减轻超拟合和过拟合的发生。对所建议的神经网络模型进行的另一项测试表明，聚合物的类型、填料的数量和进料压力对气体渗透性和选择性的影响最为显著。所提出的方法在预测天然气输运特性方面具有重要的前景，同时最大限度地减少了对大量时间和财政资源的需求。

Polyimide (PI) has been widely regarded as an ideal material for high-performance gas separation membranes due to its exceptional mechanical strength, thermal and chemical stability, excellent film-forming properties, and versatile structural tunability. However, practical applications of PI membranes have been limited by challenges such as free volume collapse, physical aging, and high gas transport resistance. These issues are considered to be addressable through the precise regulation of polymer structures via both physical and chemical modification strategies. In this review, the influence of conventional monomer structures on the gas separation performance of PI membranes is examined. Recent advances in modification techniques such as copolymerization, covalent crosslinking, thermal treatment, polymer blending, multilayer composite fabrication, and photo-induced processing are systematically discussed. The structure-property relationships resulting from these modifications are analyzed, with emphasis placed on gas transport mechanisms, as well as the advantages and limitations of each approach.

Given the growing demand for lithium in energy storage and electric vehicle industries, the development of acid-resistant membranes for efficient lithium extraction from brine and recycling of spent lithium-ion batteries is crucial for advancing sustainable and scalable resource recovery technologies. Herein, a strong acid-tolerant and positively charged polyurea (PU) nanofiltration (NF) membrane was fabricated via the interfacial polymerization of toluene-2, 4-diisocyanate (TDI) monomers with poly(allylamine) (PAA) monomers with a polyethersulfone ultrafiltration membrane as the substrate. The newly-developed typical PU NF membrane performed high cation-cation separation selectivity (mixed-salt separation factor: 16.6 for Li⁺/Mg²⁺, 19.3 for Li⁺/Ni²⁺, 11.3 for Li⁺/Co²⁺, and 15.7 for Li⁺/Mn²⁺) even if exposed to 10 wt% H₂SO₄ solution for 96 h. The high cation separation accuracy is attributed to the narrow positively-charged ion sieving channels constructed with TDI and PAA as building blocks. The urea units containing abundant bidentate hydrogen bonds and electron-rich dinitrogen atoms is responsible for the excellent acid tolerance of the PU membranes. This work has the potential to contribute to more sustainable and cost-effective lithium recovery from both brine and discarded cathode materials, making it a crucial step toward scaling up these technologies for industrial applications.

鉴于储能和电动汽车行业对锂的需求不断增长，开发用于从盐水中高效提取锂和回收废旧锂离子电池的耐酸膜对于推进可持续和可扩展的资源回收技术至关重要。本文以聚醚砜超滤膜为底物，通过甲苯- 2,4 -二异氰酸酯（TDI）单体与聚烯丙胺（PAA）单体的界面聚合制备了强耐酸、带正电的聚脲（PU）纳滤膜。新型PU纳滤膜在10 wt% H2SO4溶液中作用96 h，仍具有较高的阳离子-阳离子分离选择性（Li+/Mg2+的混合盐分离因子为16.6，Li+/Ni2+的混合盐分离因子为19.3，Li+/Co2+的混合盐分离因子为11.3，Li+/Mn2+的混合盐分离因子为15.7）。以TDI和PAA为基材构建的带正电的窄离子筛选通道具有较高的阳离子分离精度。尿素单元含有丰富的双齿氢键和富电子二氮原子，是PU膜具有优异耐酸性能的原因。这项工作有可能有助于从盐水和废弃阴极材料中更可持续、更经济地回收锂，使其成为将这些技术扩大到工业应用的关键一步。

Face masks are designed to protect the wearer from environmental hazards, such as volatile organic contaminants and suspended particulate matter (PM), which can cause asthma and anemia and affect the nervous system. This paper reports the development of a novel electrospun nanofiber membrane composite based on polyvinylidene fluoride (PVDF), polyacrylonitrile (PAN), and Piper betle extract (PLE) for potential applications in medical masks. Nanofiber membranes were fabricated via electrospinning and characterized for their physicochemical properties, antibacterial activity, and air filtration performance. SEM analysis revealed a bead-free nanofiber morphology with average diameters ranging from to 764–856 nm. The composite membranes exhibited high tensile strength over 34.92 ± 1.34 MPa, elongation at break of 1.24 % ± 0.031, and Young's modulus of 28.07 ± 1.33 MPa. Water contact angle measurements above 90° indicate the hydrophobic nature of the material. FTIR analysis confirmed the presence of phenolic compounds on the nanofiber surface, suggesting the incorporation of flavonoids, tannins, essential oils, alkaloids, and catechins from the PLE. The nanofiber membranes demonstrated effective antibacterial activity against S. aureus and P. aeruginosa, with inhibition zones of 19.65 ± 0.07 and 7.19 ± 0.08 mm, respectively, for the membrane with the highest PLE content. Air filtration tests revealed that the optimized membrane achieved a high filtration efficiency of 99.11 %, with a relatively low pressure drop of 80.28 Pa and a high-quality factor of 0.1428 Pa⁻¹. The enhanced filtration properties and low filtration resistance of the PVDF/PAN/PLE electrospun membranes demonstrated their potential for the efficient removal of particulate matter and microorganisms in air filtration applications, particularly in the development of high-performance and multifunctional medical masks.

Acid-stable nanofiltration (ASNF) membranes have emerged as a transformative technology for enabling efficient and selective separations in chemically aggressive environments encountered across various industrial sectors. Applications such as acid mine drainage treatment, copper smelting and refining, steel pickling, hydrometallurgy, biomass processing, and resource recovery require membrane systems that can withstand extreme pH levels and elevated temperatures. This review provides critical insights into the current state of ASNF membranes, particularly those developed at the bench scale, and highlights the operational limitations of conventional membranes under such harsh conditions. It examines recent progress in ASNF membrane fabrication/material design strategies, and performance metrics in extreme environments alongside the chemical mechanisms that underpin their durability. Additionally, their applications in acidic wastewater separation and recovery are examined. Challenges encountered in their development and application, with prevailing research gaps including limited long-term stability data, scalability constraints, and the absence of standardized evaluation protocols are highlighted. Finally, perspectives for future studies in academia as well as industry are recommended, including molecular-level material engineering, selective nanomaterial integration, and data-driven design approaches. By bridging fundamental membrane science with industrial relevance, this review underscores the vital role of ASNF membranes in advancing sustainable separation technologies to achieve both industrial and ecological benefits.
