The effects of solvents, polymer concentration, additive, and temperature of gel bath on the membrane performance were studied. While DMAc was used as solvent and ethylene glycol methylether or diethyl ether was used as additive, the rejection against PEG12000 was up to 100% under 0 1 MPa.展开更多
以4-(3-苯基-4-羟基苯基)-2,3-二氮杂萘-1-酮、4-(4-羟基苯基)-2,3-二氮杂萘-1-酮和4,4’-二氯二苯砜为单体,合成了一系列含侧苯基杂萘联苯聚醚砜,然后以浓硫酸为磺化剂,制备磺化含侧苯基杂萘联苯聚醚砜(SPPES-P)。采用FT-IR、1 H NMR...以4-(3-苯基-4-羟基苯基)-2,3-二氮杂萘-1-酮、4-(4-羟基苯基)-2,3-二氮杂萘-1-酮和4,4’-二氯二苯砜为单体,合成了一系列含侧苯基杂萘联苯聚醚砜,然后以浓硫酸为磺化剂,制备磺化含侧苯基杂萘联苯聚醚砜(SPPES-P)。采用FT-IR、1 H NMR对聚合物的结构进行了表征,表明磺酸基被成功地引入到聚合物侧链苯基上。采用溶液法制备了SPPES-P质子交换膜。考察了SPPES-P膜的吸水率、溶胀率、质子传导率,以及甲醇渗透性能和耐氧化性能,SPPES-P膜具有较好的阻醇性和耐氧化性能。展开更多
