    • A new series of wholly aromatic poly(arylene ether ether ketone ketone)s containing pendant sulfonic acid groups (SPAEEKK) were conveniently prepared by potassium carbonate mediated nucleophilic polycondensation reactions of inexpensive commercially available monomers: 1,3-bis(4-fluorobenzoyl)benzene (BFBB), sodium 6,7-dihydroxy-2-naphthalenesulfonate (DHNS), and 4,4′-biphenol or hydroquinone in N-methyl-2-pyrrolidone (NMP) at 170° C. FT-IR and NMR were used to characterize the structures and the sulfonate or sulfonic acid contents (SC) of the polymers. Flexible membrane films were obtained by casting N,N-dimethylacetamide (DMAc) solutions of copolymers. Membrane films in acid form were then obtained by treating the sodium form membrane films in 2 N sulfuric acid at room temperature. Glass transition temperatures (Tgs) and decomposition temperatures (Tds) of SPAEEKKs in both sodium and acid forms were determined. Water uptake and swelling ratio values increased with SCs and temperatures. The proton conductivities of acid form membrane films increased with SC value and temperature and reached 5.6×10−2S/cm at 100° C. for SPAEEKK-100.
    • 通过碳酸钾介导的亲脂性缩聚反应方便地制备了一系列含有侧基磺酸基团(SPAEEKK)的全芳香族聚(亚芳基醚醚酮酮),它们是廉价的市售单体:1,3-双(4-氟苯甲酰基)苯 (BFBB),6,7-二羟基-2-萘磺酸钠(DHNS)和4,4'-联苯酚或氢醌在N-甲基-2-吡咯烷酮(NMP)中的溶液中,使用FT-IR和NMR 以表征聚合物的结构和磺酸盐或磺酸含量(SC)。 通过浇铸N,N-二甲基乙酰胺(DMAc)共聚物溶液获得柔性膜膜。 然后通过在室温下在2N硫酸中处理钠形式的膜膜,得到酸形式的膜膜。 测定了钠和酸形式的SPAEEKK的玻璃化转变温度(Tgs)和分解温度(Tds)。 吸水率和溶胀率值随SCs和温度升高。 酸性膜膜的质子电导率随着SC值和温度的升高而升高,在100℃时达到5.6x10-2S / cm,对于SPAEEKK-100。

    • Methods for separating carbon dioxide from a fluid stream at a temperature higher than about 200° C. with selectivity higher than Knudsen diffusion selectivity include contacting a porous membrane with the fluid stream to preferentially transport carbon dioxide. The porous membrane includes a porous support and a continuous porous separation layer disposed on a surface of the porous support and extending between the fluid stream and the porous support layer. The porous support comprises alumina, silica, zirconia, stabilized zirconia, stainless steel, titanium, nickel-based alloys, aluminum-based alloys, zirconium-based alloys or a combination thereof. Median pore size of the porous separation layer is less than about 10 nm, and the porous separation layer comprises titania, MgO, CaO, SrO, BaO, La2O3, CeO2, HfO2, Y2O3, VOz, NbOz, TaOz, ATiO3, AZrO3, AAl2O4, A1FeO3, A1MnO3, A1CoO3, A1NiO3, A2HfO3, A3 CeO3, Li2ZrO3, Li2SiO3, Li2TiO3, Li2HfO3, A4N1yOz, YxN1yOz, LaxN1yOz, HfN2yOz, or a combination thereof; wherein A is La, Mg, Ca, Sr or Ba; A1 is La, Ca, Sr or Ba; A2 is Ca, Sr or Ba; A3 is Sr or Ba; A4 is Mg, Ca, Sr, Ba, Ti or Zr; N1 is V, Nb, Ta, Cr, Mo, W, Mn, Si or Ge; N2 is V, Mo, W or Si; x is 1 or 2; y ranges from 1 to 3; and z ranges from 2 to 7.
