In this research, sulfonated poly(arylene ether ketone sulfone) containing -COOH groups (C-SPAEKS) was chosen as the substrate, and ionic liquid functionalized MOFs (UiO-66-AS@ILs) were selected as fillers to prepare C-S-U-AS@ILs hybrid membranes (The term “C-S-U-AS@ILs” signifies C-SPAEKS with an incorporated ionic liquid functionalized UiO-66-AS@ILs). The UiO-66-AS@ILs and C-S-U-AS@ILs hybrid membranes were characterized by H NMR, FT-IR, PXRD and SEM. The prepared membranes exhibited suitable water uptake and swelling ratios, and the C-S-U-AS@ILs-5 % hybrid membrane possessed superior proton conductivity (0.197 S cm at 90 °C) was much higher than C-SPAEKS (0.156 S cm at 90 °C) and Nafion 117 (0.110 S cm at 90 °C). Moreover, the C-S-U-AS@ILs-5 % hybrid membranes’ power density up to 474.24 mW cm, significantly higher than that of C-SPAEKS (220.88 mW cm) under the same conditions. These results reflect that the hybrid membranes exhibited superior properties and fit the standards of proton exchange membranes.

引入离子液体浸渍MOFs制备质子传导率增强的磺化聚(亚芳基醚酮砜)质子交换膜


本研究以含-COOH基团的磺化聚芳醚酮砜（C-SPAEKS）为基材，离子液体功能化MOFs（UiO-66-AS@ILs）为填料制备了CSU-AS @ILs 混合膜（术语“CSU-AS@ILs”表示带有离子液体功能化 UiO-66-AS@ILs 的 C-SPAEKS）。通过 1H NMR、FT-IR、PXRD 和 SEM 对 UiO-66-AS@ILs 和 CSU-AS@ILs 杂化膜进行了表征。制备的膜表现出合适的吸水率和溶胀比，并且CSU-AS@ILs-5%杂化膜具有优异的质子电导率（90℃时为0.197Scm）远高于C-SPAEKS（90℃时为0.156Scm） C) 和 Nafion 117（90 °C 时为 0.110 S cm）。此外，CSU-AS@ILs-5%杂化膜的功率密度高达474.24 mW cm，显着高于相同条件下C-SPAEKS（220.88 mW cm）。这些结果表明杂化膜表现出优异的性能并符合质子交换膜的标准。
