文章采用溶剂-非溶剂扩散诱导相分离的方法，在不同制膜条件下（铸膜液聚合物含量、铸膜液温度、凝胶浴温度和凝胶浴组成）制备了PVC/SPES共混膜，并对膜的纯水通量、截留率、断裂强度、耐污染性能和膜的断面电镜扫描（SEM）等性能进行了测试，从而探讨制膜工艺条件对PVC/SPES共混膜微观结构及性能的影响。通过对不同聚合物含量的共混膜的纯水通量、截留率、机械性能和耐污染性能测试比较，得到PVC/SPES共混膜的最佳制膜条件：聚合物含量为16%，铸膜液温度为70℃，凝胶浴温度为20℃，凝胶浴为纯水。

In this paper, after blending Polyvinyl chloride(PVC) and sulfonated polyethersulfone (SPES) together, PVC/SPES bland membranes were prepared using phase inversion method under different membrane processing conditions (polymer content of the casting solution, the temperature of the casting solution, the temperature of the gel bath and the gel bath composition), and then the pure water flux, rejection rate, tensile strength, fouling resistance and scanning electron microscope(SEM) of blend membranes were tested that in order to investigate the influence of bland membranes processing conditions on PVC / SPES blend membranes microstructure and performance. By composing the pure water flux, rejection rate, tensile strength and fouling resistance of different blend membranes, then obtained PVC / SPES blend membranes optimum conditions: the optimum polymer content of the casting solution is 16%, the temperature of the casting solution is 70 ℃,  the temperature of the bath gel is 20℃, the gel bath is pour water.
