Wang, Liang;Guo, Xiang;Zhang, Feng;Li, Nanwen research published 《 Blending and in situ thermally crosslinking of dual rigid polymers for anti-plasticized gas separation membranes》, the research content is summarized as follows. The polybenzimidazoles (PBI) has been employed as blends and macromol. crosslinkers into bromomethylated polymers of intrinsic microporosity (PIM-Br) to prepare anti-plasticized gas separation membrane. Interestingly, the PBI showed excellent miscibility with PIM-Br probably due to the interaction between the benzimidazole and -CN groups, and thus a series of flexible, tough and transparent membranes were obtained by simply blending. After thermal treatment of the blending membrane, the crosslinked PIM-Br/PBI membranes with ionic and covalent crosslinking were achieved as confirmed by XPS results. Although the blending PIM-Br/PBI membranes showed the decreased gas permeabilities due to the lower gas permeability of PBI moieties, the increased gas permeabilities of PIM-Br/PBI membrane has been observed after crosslinking without significant sacrificing of selectivity. Moreover, higher crosslinking temperature induced the higher gas permeability. The PIM-Br/PBI membrane having PBI content of 5 wt% treated at 300°C has a CO2 permeability of 3313.7 Barrer which is much higher than that of the PIM-Br/PBI blending membrane (1645.3 Barrer) probably due to the formation of more open matrix in membrane after crosslinking. However, comparable CO2/CH4 selectivity of ∼13 were observed for all of the crosslinked membranes. Importantly, both of the blending and thermal crosslinking between PIM-Br and PBI resulted in the excellent CO2 anti-plasticization ability of the membrane. Particularly, a single gas plasticization pressure as high as more than 600 psi and mixed-gas plasticization resistance for crosslinked PIM-Br/PBI have been observed This value is much higher than that of the pristine PIM-Br membrane (100 psi).

Tetrafluoroterephthalonitrile is a hydroxyl group-containing organic chemical compound . It has been used in analytical chemistry as a reagent for the determination of peptide binding constants and disulfide bonds. Tetrafluoroterephthalonitrile binds to nucleophilic sites on proteins, such as the pim-1 protein, and can be used to transport other molecules across cell membranes. In addition, it has been used to produce polymers for use in analytical chemistry. This chemical is also able to bind with magnetic particles under constant pressure conditions, which makes it useful for optical sensor applications. , 1835-49-0.
