| 英文摘要 | 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6.69x10-7 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。; 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.; 福建省科技计划项目(2014H0043) |
