    聚砜/聚丙烯腈共混超滤膜性能研究

    Performance study on polysulfone-polyacrylonitrile blend ultrafiltration membranes.

    • 摘要: 本文研究了聚砜/聚丙烯腈(PSF/PAN)共混超滤膜的性能与聚合物共混比、聚合物固含量等关系。结果表明:添加聚乙二醇4000(PEG--4000)的N,N--二甲基乙酰胺(DMAC)是PSF/PAN共混体系的优良溶剂,且当聚合物的固含量为12%,水凝胶浴温度为50℃,溶剂挥发时间为30 s,m(PSF)∶m(PAN)= 8∶2时,所制得的共混超滤膜性能较好,其水通量为53 m3/(m2·h·MPa)。

       

      Abstract: This study analyzes the performance of polysulfone-polyacrylonitrile (PSF/PAN) blend ultrafiltration membranes under different blending ratios and solid contents of the polymer. The results show that N, N-Dimethylacetamide (DMAC) with the addition of polyethylene glycol 4000 (PEG-4000) is a good solvent for the blend system of PSF/PAN. When the solid content of polymer is 12%, the temperature of coagulation bath 50℃, the evaporation time 30 s, the blending ratio m(PSF)∶m(PAN)=8∶2, the performance of the blend ultrafiltration membranes is better, with a pure water flux of 53 m3/(m2·h·MPa).
