【摘要】 为了实现聚砜基阴离子交换膜（AEMs）高离子导电性和良好的耐碱性，采用绿色环保的方法制备了氯甲基化聚砜，并以氨基冠醚为交联剂，以氨基冠醚络合的金属离子和三乙胺为阳离子基团，制备了三乙胺和氨基冠醚质量分数不同的冠醚功能化聚砜膜(PSF-CE_X-QA_1-X)。通过将低分子质量的聚乙二醇（PEG）引入PSF-CE_X-QA_1-X)中，探究了PEG对膜性能的影响。结果表明，亲水PEG的存在有助于膜中离子通道的形成；与PSF-CE_X-QA_1-X相比，PSF-CE_X-QA_1-X-PEG的电导率和耐碱稳定性均得到了提高；在温度为80℃时，PSF-CE_0.1-QA_0.9-PEG的电导率为56.78 mS/cm，耐碱性测试后其电导率可维持初始电导率的85%。此外，PSF-CE_X-QA_1-X-PEG还具有良好的尺寸稳定性和热稳定性。更多还原

【Abstract】 In order to achieve high ionic conductivity and good alkaline resistance of Polysulfone-based AEMs,chloromethylated polysulfone was prepared by green method,and crown ether-functionalized polysulfone membranes with different triethylamine and amino crown ether contents were then prepared using amino crown ether as cross-linking agent and metal ions and triethylamine as cationic groups followed by crown ether functional polysulfone membrane with triethylamine and triethylamine as cationic groups(PSF-CE_X-QA_1-X).The effect of the addition of polyethylene glycol on the membrane properties was explored by introducing the low molecular weight polyethylene glycol（PEG） into the above polysulfone cross-linking membrane.The results shown that the presence of hydrophilic polyethylene glycol helps to facilitate the formation of ordered ion channels in the membrane.The conductivity and alkali-resistant stability of PSF-CE_X-QA_1-X-PEG were improved compared to PSF-CE_X-QA_1-X membrane.Among them,the electrical conductivity of PSF-CE_0.1-QA_0.9-PEG at 80℃ is 56.78 mS/cm,which can retain 85%of the original conductivity after alkaline resistance test.In addition,PSF-CE_X-QA_1-X-PEG has good dimensional and thermal stability.更多还原
