摘要：

将磺化杂萘联苯共聚醚砜浸泡于盐溶液中制备得到磺酸盐型杂萘联苯共聚醚砜（SPPBES-M），对其进行FT-IR和TGA表征。SPPBES-M的5%热失重温度高于489 ℃，具有优异的热稳定性。采用涂覆法制备SPPBES-M/PPBES复合纳滤膜，考察了浸涂液中SPPBES-M浓度、反离子种类、热处理温度以及热处理时间对复合纳滤膜性能的影响。结果表明，随着反离子（Li+、Na+和K+）离子半径增大，SPPBES-M/PPBES复合膜的通量由29 L/(m2·h)增加到36 L/(m2·h)，其脱盐率由65%降低至58%；随着热处理时间和热处理温度升高，复合膜的水通量降低而脱盐率升高，当热处理时间由10min延长至40min，SPPBES-100-K/PPBES复合膜的脱盐率由62%提高至83%。

Sulfonated copoly(phthalazinone biphenyl ether sulfone) substituted by counterions (SPPBES-M) were prepared from sulfonated copoly(phthalazinone biphenyl ether sulfone) (acid form) immersing in salt solutions. SPPBES-M were characterized by FT-IR and TGA. The 5% decomposition temperature of SPPBES-M was higher than 489 ℃, and SPPBES-M had excellent thermal stability. SPPBES-M/PPBES composite nanofiltration membranes were prepared by coating method. The effects of SPPBES-M concentration, counterions, curing treatment temperature, and curing treatment time on the performance of composite nanofiltration membranes were investigated. The rejection of composite membrane decreased from 65% to 58%, and the flux increased from 29 L/(m2·h) to 36 L/(m2·h) with the increase of the radius of counterions (Li+、Na+ and K+). With the increase of curing treatment temperature and time, the water flux of SPPBES-100-M/PPBES composite membranes were decreased, and the rejection were increased. When the curing treatment time extended from 10min to 40min, the rejection enhanced from 62% to 83%.
