Defect engineering allows for precise control of the microporous structure and coordination defects in metal-organic frameworks (MOFs). This approach offers an innovative pathway to optimize the gas separation performance of MOF/polymer mixed matrix membranes (MMMs). Herein, UiO-PzDC nanoparticles with gradient defects were synthesized by substituting terephthalic acid with 2,5-pyrazinedicarboxylic acid (PzDC) as a linker in a novel UiO-66 derivative, while modulating the defect concentration through the addition of 2-pyrazinecarboxylic acid (2-PZC). The material was dispersed within a highly permeable polymer matrix (e.g., PIM-1), and the influence of defect concentration on the interfacial properties and mass transfer behavior of mixed matrix membranes (MMMs) was systematically investigated. Combined analysis of experimental results and molecular dynamics simulations demonstrated that the incorporation of PzDC ligands significantly enlarged the MOF pore size, while the 2-PZC-induced defects further enhanced the microporous connectivity. Owing to the synergistic effect of MOF defects and the PIM-1 matrix, the composite membranes demonstrated superior filler-matrix interfacial compatibility, and the defect concentration exhibited no significant influence on interfacial stability. Gas transport studies revealed that the defect-engineered MOF facilitated an ultrafast transport channel for CO2 through enhanced diffusion selectivity. MMMs containing a high defect concentration of UiO-PzDC (defectivity: 3.03) exhibit breakthrough separation performance, achieving a CO2 permeability of 18,553 Barrer (a 384 % improvement over pure PIM-1) and a CO2/N2 selectivity of 23. This performance combination surpasses the 2019 Robeson upper bound. This study elucidates the universal principle of ligand substitution and defect engineering in synergistically modulating the mass transfer mechanism of metal-organic frameworks (MOFs), establishing a novel paradigm for designing next-generation membrane materials that simultaneously exhibit high permeability and selectivity.
缺陷工程可以精确控制金属有机骨架（MOFs）的微孔结构和配位缺陷。该方法为优化MOF/聚合物混合基质膜（MMMs）的气体分离性能提供了一条创新途径。本文以2,5-吡嗪二羧酸（PzDC）为连接剂，在新型UiO-66衍生物中取代对苯二甲酸，并通过添加2-吡嗪二羧酸（2- pzc）调节缺陷浓度，合成了具有梯度缺陷的UiO-PzDC纳米颗粒。将材料分散在高渗透性聚合物基体（如PIM-1）中，系统地研究了缺陷浓度对混合基质膜（MMMs）界面性能和传质行为的影响。结合实验结果和分子动力学模拟分析表明，PzDC配体的掺入显著增大了MOF的孔径，而2- pzc诱导的缺陷进一步增强了微孔的连连接性。由于MOF缺陷与PIM-1基质的协同作用，复合膜具有较好的填料-基质界面相容性，缺陷浓度对界面稳定性无显著影响。气体输运研究表明，缺陷设计的MOF通过增强扩散选择性，促进了CO2的超快输运通道。含有高缺陷浓度UiO-PzDC（缺陷率：3.03）的MMMs表现出突破性的分离性能，实现了18553 Barrer的CO2渗透率（比纯PIM-1提高了384%）和23的CO2/N2选择性。这一业绩组合超过了2019年罗布森上限。本研究阐明了配体取代和缺陷工程在协同调节金属有机骨架（mof）传质机制中的普遍原理，为设计同时具有高渗透性和选择性的下一代膜材料建立了新的范例。

The rational design of chemical-physical/geometric structures of membrane surface is the key for fabricating antifouling oil-water separation membranes. Herein, we propose a nanosphere-mediated surface segregation strategy to construct dual-heterogeneous antifouling membranes. The casting solution employs Pluronic F127 covalently grafted with hexafluorobutyl methacrylate (F127-F) as the surface segregation agent, while TA-APTES nanospheres (TAP NPs) are introduced in the coagulation bath as the crosslinking agent. During the NIPS process, the hydrogen bonding interactions between TAP NPs and F127-F promote the in-situ self-assembly of a dual-heterogeneous surface with controllable physical topology and hydrophilic-low surface energy composition. The resulting oil-water separation membrane achieves a pure water permeance of 543.17 ​L ​m−2 ​h−1 bar−1, along with an ultralow permeance decline ratio of 0.34 ​% and a 100 ​% flux recovery ratio. Besides, the membrane displays excellent self-cleaning capability against crude oil.
膜表面化学-物理/几何结构的合理设计是制备防污油水分离膜的关键。在此，我们提出了一种纳米球介导的表面分离策略来构建双异质防污膜。浇注液采用Pluronic F127与六氟甲基丙烯酸丁酯（F127- f）共价接枝作为表面隔离剂，在混凝液中引入TA-APTES纳米球（TAP NPs）作为交联剂。在NIPS过程中，TAP NPs与F127-F之间的氢键相互作用促进了具有可控物理拓扑和亲水性低表面能组成的双非均相表面的原位自组装。所得油水分离膜的纯水渗透率为543.17 L m−2 h−1 bar−1，超低渗透下降率为0.34%，通量回收率为100%。此外，该膜对原油具有良好的自清洁能力。
