Chen, Xiuling;Fan, Yanfang;Wu, Lei;Zhang, Linzhou;Guan, Dong;Ma, Canghai;Li, Nanwen research published 《 Ultra-selective molecular-sieving gas separation membranes enabled by multi-covalent-crosslinking of microporous polymer blends》, the research content is summarized as follows. High-performance membranes exceeding the conventional permeability-selectivity upper bound are attractive for advanced gas separations In the context microporous polymers have gained increasing attention owing to their exceptional permeability, which, however, demonstrate a moderate selectivity unfavorable for separating similarly sized gas mixtures Here we report an approach to designing polymeric mol. sieve membranes via multi-covalent-crosslinking of blended bromomethyl polymer of intrinsic microporosity and Troger’s base, enabling simultaneously high permeability and selectivity. Ultra-selective gas separation is achieved via adjusting reaction temperature, reaction time and the oxygen concentration with occurrences of polymer chain scission, rearrangement and thermal oxidative crosslinking reaction. Upon a thermal treatment at 300°C for 5 h, membranes exhibit an O₂/N₂, CO₂/CH₄ and H₂/CH₄ selectivity as high as 11.1, 154.5 and 813.6, resp., transcending the state-of-art upper bounds. The design strategy represents a generalizable approach to creating mol.-sieving polymer membranes with enormous potentials for high-performance separation processes.

Chen, Xiuling;Wu, Lei;Yang, Huimin;Qin, Yong;Ma, Xiaohua;Li, Nanwen research published 《 Tailoring the Microporosity of Polymers of Intrinsic Microporosity for Advanced Gas Separation by Atomic Layer Deposition》, the research content is summarized as follows. Tailoring the microporosity of intrinsically microporous polymers at the at. level is one of the biggest challenges in achieving high-performance polymeric gas separation membranes. In this study, for the first time, the Al₂O₃ at. layer deposition (ALD) technique was used to modify the microporosity of a typical polymer of intrinsic microporosity (PIM-1) at the at. level. PIM-1 with six ALD cycles (PIM-1-Al₂O₃-6) exhibited simultaneous high thermal, mech., pure- and mixed-gas separation, and anti-aging properties. The O₂/N₂, H₂/N₂, and H₂/CH₄ separation performances were adequate above the latest trade-off lines. PIM-1-Al₂O₃-6 showed CO₂ and O₂ permeabilities of 624 and 188 Barrer, combined with CO₂/CH₄ and O₂/N₂ selectivities of 56.2 and 8.8, resp. This significantly enhanced performance was attributed to the strong size sieving effect induced by the Al₂O₃ deposition.

Chen, Xiudong;Zhang, Hang;Yan, Ping;Liu, Bo;Cao, Xiaohua;Zhan, Changchao;Wang, Yawei;Liu, Jin-Hang research published 《 Bipolar fluorinated covalent triazine framework cathode with high lithium storage and long cycling capability》, the research content is summarized as follows. Organic materials with adjustable structures and wide sources are expected to become potential candidates for com. cathodes of lithium-ion batteries (LIBs). However, most organic materials have unstable structures, poor conductivity, and are easily soluble in electrolytes, resulting in unsatisfactory lithium storage performance. Covalent-organic frameworks have attracted extensive attention due to their stable frame structures, adjustable pore structures and functionalized official groups. Herein, a fluorinated covalent triazine framework (FCTF) is synthesized by a simple ion-thermal method. Compared with the fluorine-free covalent triazine frameworks (CTFs), the introduction of fluorine improves the lithium storage performance of CTF. When used as a cathode for lithium ion batteries, FCTF can retain a reversible capacity of 125.6 mA h g^-1 after 200 cycles at a c.d. of 100 mA g^-1. Besides, it also delivers 106.3 mA h g^-1 after 400 cycles at a c.d. of 200 mA g^-1 with 0.03% decrease per cycle (from 40 to 400 cycles).

Chen, Xinggang;Cai, Yanqing;Qu, Xiongwei;Chen, Jun;Zheng, De research published 《 Preparation of a self-catalyzed amino-epoxy phthalonitrile resin with a large processing window》, the research content is summarized as follows. To expand the processing window of phthalonitrile resins, a novel self-catalyzed amino-epoxy 4-aminophenoxy phthalonitrile-resorcinol diglycidyl ether phthalonitrile (APRE-PN) resin was prepared via a two-step method of reacting amino and epoxy groups at a low temperature and then reacting nitrile with nitrile groups at a high temperature The amine-epoxy, epoxy-nitrile, and nitrile-nitrile reactions were confirmed by Fourier-transform IR spectroscopy and differential scanning calorimetry, and the probable polymerization mechanism was elucidated. The significant decrease in the m.p. of the proposed APRE-PN prepolymers dramatically expands the processing window (173°C) for an entire class of phthalonitrile matrixes. The APRE-PN resin exhibits excellent thermal stability and dynamic mech. properties owing to the presence of triazine, phthalocyanine, and oxazoline structures. The improved preparation method provides a new path for the preparation of phthalonitrile resins with large processing windows and new opportunities for the use of this type of thermosetting matrix in manufacturing various composite materials and prepregs.

Chen, Wenbo;Zhang, Zhenguo;Yang, Cancan;Liu, Jing;Shen, Hongcheng;Yang, Kai;Wang, Zhe research published 《 PIM-based mixed-matrix membranes containing MOF-801/ionic liquid nanocomposites for enhanced CO₂ separation performance》, the research content is summarized as follows. In this work, we fabricated PIM-based mixed matrix membranes (MMMs) containing MOF-801/ionic liquid nanocomposites to enhance CO₂ separation performance of pure polymer membranes. All membranes and MOF-801/ionic liquid nanocomposites were prepared by solution casting method and wet impregnation, resp. The samples were analyzed by SEM, XRD, FTIR, TGA and Nitrogen adsorption-desorption measurements. The nanocomposites are composed of metal-organic framework (MOF) MOF-801 and ionic liquid (IL) adsorption capacity. MOF-801 can well control the dispersion of IL in the polymer matrix, which is conducive to exposing more active sites in the nanocomposites to improve the CO₂ adsorption selectivity of MOF-801/ionic liquid nanocomposites. At the same time, the porous structure of nanocomposites also enhances the gas adsorption and diffusion, thereby improving the gas separation performance. Compared with pure PIM-1 membranes, the CO₂ permeability and CO₂/N₂ selectivity of IL@MOF/PIM-5% MMMs was increased by 129% and 45% (CO₂ = 9420 Barrer, CO₂/N₂ = 29), resp. Compared with MOF-801/PIM-1 MMMs, the permeability of CO₂ decreased slightly but the selectivity of CO₂/N₂ increased from 27 to 29. The aging test showed that the CO₂ permeability of MMMs could remain above 70% after 90 days. The anti-plasticization performance of MMMs has also been significantly improved. The CO₂ separation performance of IL@MOF/PIM-5% MMMs significantly exceeded the 2008 Robeson upper bound, showing excellent gas separation performance and working stability.

Charge transfer (CT) complexes of 4,4′-bis(9H-carbazol-9-yl)-1,1′-biphenyl (CBP) and three acceptors emitted cyan, green and orange fluorescence and lower LUMO energy levels of acceptors promoted longer emission wavelengths. Moreover, they could reversibly convert their luminescent colors under force and then fuming by chlorinated hydrocarbon solvents. Amazingly, acetonitrile vapor annealing might decompose CT complexes to form pure CBP crystalline phase, which induced sharp changes in fluorescence colors. As a result, a largest emission shift was more than 220 nm. CT complexes could also be formed through pressing the mixture of donor and acceptor and the emission color gradually changes from blue to cyan, green, white, yellow, orange and even red with extending grinding time, realizing the full color luminescence in the visible light region. Owing to their excellent stimuli-responsive behaviors, anticounterfeiting papers with two fluorescent colors have been constructed. Moreover, fluorescence colors of papers could be reversibly transformed under solvent annealing treatment. High-resolution patterns in both papers might be written by stylus printer and be erased by solvent fuming with high reversibility.
