摘　　要：利用国内近几年开发的新型膜材料,选择适当的共混聚合物体系,可以制得性能优良的共混膜。本文通过共混方式,制得了孔径较小的共混超滤膜。详细研究了聚醚砜-磺化聚砜共混材料的相溶性、铸膜液组成、蒸发时间和凝胶温度等因素对共混超滤膜分离特性与形态结构的影响。PES-SPS Blend UF membrane prepared from casting solution which consisted of DMAC and blend polymer of PES and SPS was studied in this paper. Effect of casting solution composition, evaporation time and coagulation temperature etc. For forming of UF membrane on permeation performances were investigated. The morphological structure of PES-SPS blend UF membranes were examined.
