进行了ＰＡＡ（ＰｏｌｙａｃｒｙｌｉｃＡｃｉｄ）－ＰＳＦ（Ｐｏｌｙｓｕｌｆｏｎｅ）交联复合膜的制备，研究了交联剂、添加剂对膜性能的影响，并通过扫描电镜观察了膜的断面结构．研究了ＰＡＡ－ＰＳＦ交联复合膜对低浓度有机醇类水溶液反渗透分离性能．发现对于１０００×１０－６乙醇水溶液截留率达到６６．２％，透过流束可达０．９×１０－６（ｍ３·ｍ－２·ｓ－１）．随醇的分子量的增加，截留率不断上升，对戊醇的截留率达９４．３％，而透过流束则保持相对稳定．对不同结构醇类的分离性能研究表明，截留率存在有：ｔｅｒｔ－＞ｓｅｃ－＞ｉｓｏ－＞ｎ－的规律．
Polyacrylic Acid-PSF (Polysulfone) crosslinked composite films were prepared. The effects of crosslinking agents and additives on the properties of the films were studied. The cross-sectional structure of the films was observed by scanning electron microscopy. The reverse osmosis separation performance of PAA-PSF crosslinked composite membrane on low concentration organic alcohol aqueous solution was studied. It was found that the permeation flux was up to 0.9 × 10-6 (m3 · m-2 · s-1) for the 66.2% rejection of 1000 × 10-6 ethanol aqueous solution. With the increase of the molecular weight of the alcohol, the retention rate increased, the retention rate to amyl alcohol reached 94.3%, while the permeation flux remained relatively stable. Studies on the separation performance of alcohols with different structures show that there are some rules of tert-> sec-> iso-> n-.
