中文摘要：
以杂萘联苯聚醚砜（PPES）为膜材料，N-甲基吡咯烷酮为溶剂，丙酸（PAc）、乙醚（EE）和丙醇（PAL）为非溶剂添加剂，采用相转化法制备了PPES超滤膜．结果表明：在0．1MPa的操作压力下，以EE为添加剂时，随着邻近比α值的增加，膜的纯水通量减小，对PEG10000截留率基本保持在99％；以PAL为添加剂时，随着邻近比α值的增加，膜的纯水通量呈现先增大后减小的趋势；以PAc为添加剂时，随着邻近比α值的增加，膜的水通量增加，截留率略有降低，膜的断面结构由指状孔结构向海绵状孔结构转变．
英文摘要：
The ultrafiltration membranes were prepared successfully from poly （phthalazinone ether sulfone） （PPES） with a phase inversion technique. Ether, propanol and propyl acid were used as nonsolvent additives （NSA） and N methyl - 2 - pyrrolidone（NMP） was used as solvent in the membrane preparation. Under the operating pre~ure of 0.1 MPa, when the NSA was ether, water flux decreased and got the rejection rate of 99% with the increase of a value; when propanol was used as NSA, water flux increased then decreased; when the NSA was propyl acid, it is found that the increase of a value could lead to the changing of membrane structure form finger to sponge, an increase of water flux and a decrease of reiection.
