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.

Searching for outstanding films with high temperature resistance has sparked fierce interests in the electronics industry. In this study, a novel high-temperature-resistance phthalonitrile end-capped polyarylene ether nitrile (HTR-PEN-Ph) film was fabricated via crosslinking reaction, applying two different curing programs as contrast. The fabricated HTR-PEN-Ph films were verified through FTIR, gel content test to be confirmed the crosslinking reaction.

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.
