摘要

摘要: 通过共混的方法制备了含笼型聚倍半硅氧烷(POSS)星型拓扑结构嵌段共聚物的氧化石墨烯(GO)/笼型聚倍半硅氧烷-(聚甲基丙烯酸甲酯-共聚-磺化聚苯乙烯)(POSS-(PMMA₂₆-b-SPS₁₅₆)₈)复合质子交换膜。通过研究复合质子交换膜的离子交换容量(IEC)、质子传导率、吸水率与溶胀率,考察了GO含量对复合质子交换膜性能的影响。研究发现:复合质子交换膜的离子交换容量随GO含量的增加而升高,吸水率和溶胀率随着GO加入而降低,在测定温度范围内复合质子交换膜均表现出较高的尺寸稳定性,GO的添加改善了纯聚合物膜在80℃失水导致传导率下降的问题,提高了质子交换膜的质子传导率,发现在相对湿度为100%、80℃时,GO含量为0.3wt%的复合质子交换膜的质子传导率约为纯聚合物膜的3.2倍。

Abstract: Blend proton exchange membrane with polyhedral oligomeric silsesquioxane (POSS) star topological structure block copolymer graphene oxide (GO)/polyhedral oligomeric silsesquioxane-(polymethylmethacrylate-block-polystyrene)(POSS-(PMMA₂₆-b-SPS₁₅₆)₈) was prepared by the blending method. The effects of GO content on the properties of blend proton exchange membrane were investigated by testing ion exchange capacity (IEC), proton conductivity, water uptake and swelling rate. It is found that the ion exchange capacity of the blend proton exchange membrane increases with the increase of GO content, while water uptake and swelling rate reduce with adding GO. The blend proton exchange membrane shows higher dimensional stability in the determination of temperature range. The decline of the conductivity of pure polymer membranes owing to water loss in 80℃ can be improved by adding GO. The proton conductivity of proton exchange membrane can be improved, It is found that the proton conductivity of the blend proton exchange membrane with 0.3wt% content of GO is approximately 3.2 times bigger than that of the pure polymer membranes in 100% relative humidity at 80℃.
