| 摘 要： | 采用共混制备了一系列磺化含酚酞侧基聚芳醚酮(SPEK-C)/氧化石墨烯(GO)复合质子交换膜,系统地研究了GO含量对复合膜性能的影响。结果表明,GO含量对膜的离子交换容量、稳定性、质子电导率和甲醇渗透率等有重要影响。复合膜质子电导率随GO含量增加而提高,GO含量为2%和5%的复合膜在80℃下质子电导率均在10-1 S·cm-1以上。80℃下,GO含量为5%的复合膜甲醇渗透率为6.69×10-7 cm2·s-1,低于同温度下复合前SPEK-C膜1个数量级。复合后膜的化学稳定性增强,离子交换容量和含水率均有提高,相对选择性明显增大,最高达SPEK-C的18.2倍。

| Abstract: | A series of sulfonated phenolphthalein side poly (aryl ether ketone) (SPEK-C)/graphene oxide (GO) hybrid composite proton exchange membranes was fabricated. The effect of GO as a filler blending with SPEK-C was investigated systematically. The results indicated that GO content in the membrane had a great influence on ionic exchange capacity, stability, proton conductivity and methanol permeability. The proton conductivity was enhanced with increasing GO content. Moreover, the proton conductivity of the composite membranes with 2% and 5% GO was all above 10-1 S·cm-1 at 30℃. The composite membrane containing 5% GO exhibited methanol permeability of 6.7×10-8 cm2·s-1 at 30℃, which was one order of magnitude lower than that of SPEK-C membrane. The ionic exchange capacity, stability and water uptake were enhanced, and the relative selectivity reached up to 18.2 times higher than that of the SPEK-C membrane. |
