聚醚砜合成膜的结构与性能研究

Study on structure and performance of polyethersulfone membrane

以截流率、水通量为指标,分别讨论了几种非溶剂型添加剂对聚醚砜复合超滤膜性能的影响,通过扫描电子显微镜观察了其结构,并阐述了结构与性能的关系。结果表明,w(SiO_2)为20%、w(PEG1000)为3%、w(PVP)为1%和w(MPC1501)为3%时,综合性能最好。

The performance of the polyethersulfone ultrafiltration membrane were discussed for several nonsolvent additives by retention and water flux.The structure of the polyethersulfone membrane were confirmed by scanning electron microscope（SEM）.And the relationship between structure and properties was described.The result show that performance of the membrane is the best when w（SiO_2） is 20%,w（PEG10000） is 3%,w （PVP） is 1%and w（MPC1501） is 3%.
