He, Xian;Qi, Jiayue;Chen, Menghao;Lv, Jiangbo;Xiao, Hang;Hu, Jianghuai;Zeng, Ke;Yang, Gang research published 《 Preparation of novel bio-based imine-containing phthalonitrile resin through the nucleophilic reaction in green solvent》, the research content is summarized as follows. Nucleophilic reactions, as extensive and easily implementable reactions in organic chem., play a significant role in the mol. design of organic compounds and polymer materials. In current sustainable development strategies, nucleophilic reactions are also being shifted towards green chem. In this paper, phthalonitrile (PN) resin, a thermoset prepared by nucleophilic substitution reaction, was selected for a case study to investigate the application and reusability of the ‘green solvent’ di-Me carbonate (DMC) in the nucleophilic substitution reaction. This research employed naturally existing vanillin and tyramine for the synthesis of a fully bio-based bisphenol bearing a Schiff base structure (VTBP). Then VTBP was converted to a novel bio-based PN (VTPN) through a nucleophilic substitution reaction in DMC, and the DMC was recovered and reused through a rotary evaporation The structure, curing behavior, and performance of the cured resin of the synthesized VTPN were characterized. The results suggest that the Schiff base may promote and participate in the crosslinking of nitrile, with a relatively high performance achieved under moderate curing conditions. This study provides a new green implementation scheme for high-performance polymers prepared through nucleophilic reactions, as well as for the high-performance and efficient utilization of widely existing bio-based aldehydes and amines.

He, Shanshan;Zhu, Bin;Jiang, Xu;Han, Gang;Li, Songwei;Lau, Cher Hon;Wu, Yadong;Zhang, Yanqiu;Shao, Lu research published 《 Symbiosis-inspired de novo synthesis of ultrahigh MOF growth mixed matrix membranes for sustainable carbon capture》, the research content is summarized as follows. Mixed matrix membranes (MMMs) are one of the most promising solutions for energy-efficient gas separation However, conventional MMM synthesis methods inevitably lead to poor filler-polymer interfacial compatibility, filler agglomeration, and limited loading. Herein, inspired by symbiotic relations in nature, a universal bottom-up method is designed for in situ nanosized metal organic framework (MOF) assembly within polymer matrixes. Consequently, the method eliminating the traditional postsynthetic step significantly enhanced MOF dispersion, interfacial compatibility, and loading to an unprecedented 67.2 weight% in synthesized MMMs. Utilizing exptl. techniques and complementary d. functional theory (DFT) simulation, it is validated that these enhancements synergistically ameliorated CO₂ solubility, which was significantly different from other works where MOF typically promoted gas diffusion. The approach simultaneously improves CO₂ permeability and selectivity, and superior carbon capture performance is maintained even during long-term tests; the mech. strength is retained even with ultrahigh MOF loadings. This symbiosis-inspired de novo strategy can potentially pave the way for next-generation MMMs that can fully exploit the unique characteristics of both MOFs and matrixes.

Han, Xiaocui;Chen, Liyuan;Wang, Yan;Wang, Tianjiao;Cui, Fengchao;Jiang, Zhenhua;Pang, Jinhui research published 《 Novel Polymers with Ultrapermeability Based on Alternately Planar and Contorted Units for Gas Separation》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs) have been the potential candidates as gas separation membrane materials, because of their high permeability and good processing. Here, three PIMs (PIM-ABAs) with ultrahigh permeability are reported; these are significantly more permeable than the PIM-1 and other PIMs reported and do not lose high selectivity and good processing merit. The introduction of large and rigid planar units alternatively contorted units suppresses the compact packing of polymer chains, resulting in the hierarchical porosity range of 0.5-4.0 nm. The presence of larger pores is responsible for promoting permeability. PIM-ABA-OMEN demonstrates the optimal CO₂ permeability (16 736 barrer), which is 3.95 times more than PIM-1 (4234 barrer) with equivalent gas selectivity and PIM-ABA-EN exhibits the promotion of both permeability and selectivity. After being aged for 186 days, PIM-ABAs still showed the CO₂ permeability above 8000 barrer, which is almost as 2 times greater than that of unaged PIM-1. This work provides a new strategy for the preparation of PIMs with enhanced gas separation performance.

Han, Weiyao;Zhang, Caili;Zhao, Min;Yang, Fan;Yang, Yang;Weng, Yunxuan research published 《 Post-modification of PIM-1 and simultaneously in situ synthesis of porous polymer networks into PIM-1 matrix to enhance CO₂ separation performance》, the research content is summarized as follows. Post-modification of the chem. structures can be used to tailor the properties of polymers of intrinsic microporosity (PIM-1), which shows promise for application of PIM-1 gas separation membrane. Methane sulfonic acid (MSA) is capable of hydrolyzing and crosslinking nitrile groups of PIM-1 to form carboxylic acid-contained and triazine groups crosslinked PIM-1 (cPIM-1), and simultaneously catalyze in situ synthesis of porous polymer networks (PPNs) in PIM-1 matrix. These reactions were carried out at the same time by a one-step method. Characterization of hydrolysis and crosslinking process of nitrile groups in PIM-1 was performed by ATR, XPS, solubility, and ¹H NMR anal. MSA catalyzed synthetic approach of PPNs includes the trimerization of three acetyl groups and involves a coupled process of polymerization and membrane architecture formation. Finally, the process of crosslinking and hydrolysis can provide enhanced gas pair selectivity of PIM-1 membrane (cPIM-1) while the gas permeability of the membranes (cPIM-1/PPNs) can be increased by the incorporation of PPNs microstructure networks. As a result, the optimal cPIM-1/PPNs showed Roberson’s 2008 upper bound separation performance for CO₂/CH₄ and CO₂/N₂. The cPIM-1/PPN2-3% membrane demonstrated the best CO₂ comprehensive separation performance with the permeability of almost 11511 Barrer, with ideal selectivity of 24.3 and 22.2 for CO₂/N₂ and CO₂/CH₄ resp. Furthermore, the cPIM-1/PPNs membranes show excellent anti-aging properties. This indicates that MSA-catalyzed hydrolysis, crosslinking and in situ synthesis PPNs can effectively adjust the topol. structure of PIM-1 membrane for CO₂ separation

Han, Jiuli;Jiang, Haiyan;Zeng, Shaojuan;Bai, Yinge;Zhang, Xiangping;Bai, Lu research published 《 CO₂ separation performance for PIM based mixed matrix membranes embedded by superbase ionic liquids》, the research content is summarized as follows. Mixed matrix membranes (MMMs) have drawn much interest in CO₂ separation due to their excellent separation performance, mech. property, and desirable processability. However, obtaining highly compatible MMMs is a great challenge and is vital to avoid the loss of the separation selectivity of the MMMs. In this work, superbase ionic liquid (1,8-diazabicyclo[5,4,0]undec-7-ene imidazole ([HDBU][Im])) was used as a wetting agent to increase the interfacial compatibility between ZIF-67 and PIM-1, hence improving the membrane gas separation [HDBU][Im] embeding into the MMMs could efficiently enhance the compatibility and diminish the interfacial voids. Furthermore, incorporating 5 wt% [HDBU][Im]@ZIF-67 nanocomposite into the PIM-1 matrix improves the gas permeability and CO₂ selectivity. The separation performances under the different temperatures were also conducted and showed that reducing temperature slightly decreases the gas permeability but significantly increases the CO₂/CH₄ selectivity via enhancing the CO₂ solubility The permeation active energies, diffusivities and solubilities were obtained to explain the gas permeate mechanism.
