CN105107395A — 中空介孔氧化硅球/聚醚砜复合超滤膜的制备方法

Assigned to Nanjing University of Science and Technology · Expires 2015-12-02 · 10y expired

What this patent protects

本发明公开了一种中空介孔氧化硅球/聚醚砜复合超滤膜的制备方法。所述超滤膜通过将分散良好的中空介孔氧化硅球共混于聚醚砜体系，再利用相转化法制备得到。本发明中的中空介孔氧化硅球具有的介孔孔道和中空结构为水分子快速通过提供了途径，从而改善了聚醚砜超滤膜的通量；且本发明中的中空介孔氧化硅球表面富含羟基，将其共混于聚醚砜中能改善膜的亲水性及抗污染能力。
