摘　　要：采用粘度法和红外光谱法研究聚丙烯腈(PAN)/聚砜(PS)的相容性,研究聚合物组成、共混物浓度、添加剂、凝胶浴等对PAN/PS共混膜的水通量和截留率的影响。采用扫描电镜分析PAN/PS共混膜的显微结构。结果表明:PAN/PS共混膜与PAN膜具有相似的化学稳定性,但较PAN膜具有更好的分离和透过特性。The compatibility of PAN/PS was investigated by the method of viscosity and infrared spectrometry. The PAN/PS blended ultrafiltration membranes prepared with casting solution were characterized by SEM, retention rate and water flux. The results indicated that the chemical stability of PAN/PS membrane was similar to the PAN membrane, but PAN/PS membranes possessed much higher water flux and better separation performance than these of PAN membrane.
