摘要

本文通过酰胺化反应对两性阴离子ADPS在UiO-66-COOH上进行改性，并将所制得的功能性UiO-66-ADPS添加到磺化聚芳醚酮砜（SPAEKS）基体中，成功制备了SPAEKS-UiO-66-ADPS（简称SPAEKS- u - a - x %）系列复合膜。对UiO-66-ADPS及其系列复合膜进行了表征和评价。所制备的复合膜具有优异的电化学性能、优异的吸水性和力学性能。其中，在90°C时，SPAEKS- u - a - 0.75%的质子电导率达到268.31 mS cm - 1，功率密度为1553.10 mW/cm2，远高于SPAEKS膜的302.65 mW/cm2。结果表明，UiO-66-ADPS显著提高了PEMs的电化学性能。

Construction of high conductivity poly(aryl ether ketone sulfone) proton exchange membrane by incorporating zwitterion-modified MOFs

In this paper, the zwitterion ADPS was modified on UiO-66-COOH by amidation reaction, and the functional UiO-66-ADPS that was produced was added to the matrix of sulfonated poly(aryl ether ketone sulfone) (SPAEKS), and the series of composite membranes of SPAEKS-UiO-66-ADPS (abbreviated as SPAEKS-U-A-X%) were successfully prepared. The UiO-66-ADPS and the series of composite membranes were characterized and evaluated. The composite membranes created exhibit excellent electrochemical performance, as well as superior water uptake and mechanical properties. Among them, at 90 °C, the proton conductivity of SPAEKS-U-A-0.75 % reached 268.31 mS cm⁻¹, and the power density was 1553.10 mW/cm², which was much higher than that of the SPAEKS membrane (302.65 mW/cm²). The results show that UiO-66-ADPS significantly improved the electrochemical performance of the PEMs.
