【摘要】 通过溶液共混的方法,以自制的高磺化度聚醚砜(ABPSNa-10)和磺化聚苯并咪唑(S-PBI)为原料,二甲基亚砜(DMSO)为溶剂,制备了酸碱复合膜,并研究了膜的组成对膜的甲醇溶胀性、甲醇渗透系数和质子传导率的影响,研究表明,复合膜具有良好的质子传导率,同时,随着S-PBI含量的增加,膜的阻醇性能和尺寸稳定性明显提高。更多还原

【Abstract】 A series of blend membranes from sulfonated Poly(arylene ether sulfone)(S-PSU) and sulfonated polybenzimidazole(S-PBI) were prepared via blend.The properties of membranes were characterized in terms of swelling ratio in methanol aqueous solution,methanol permeability coefficient and proton conductivity.The results showed that introduction of PBI reduced the methanol swelling and methanol permeability coefficient of membranes. Furthermore,with the increase of S-PBI content,the methanol permeability coefficient of the blend membranes decreased.更多还原
