摘　　要：以聚偏氟乙烯(PVDF)为第二组分聚合物与三醋酸纤维素(CTA)共混,通过冻胶法纺丝工艺制备成中空纤维纳滤膜。讨论了固含量,纺丝工艺和后处理条件对膜性能的影响,并测试了不同操作条件下的膜性能,取得了满意的结果。Hollow fiber NF membrane was prepared with blending of PVDF as the second component polymer and CTA, and by spinning process with gelation method. The effect of solid content, spinning process and post-treatment conditions on membrane performance was discussed. The membrane performance under different operating conditions was determined, and the results are satisfactory.
