摘要
聚砜中空纤维膜可用作水处理的超滤膜及纳滤膜等,也可用作血液透析膜。但聚砜中空纤维膜存在亲水性差、超滤率低、易吸附蛋白等缺点,因此需要通过改性进行性能提高。本文对聚砜中空纤维膜的改性工艺及效果进行了介绍分析,并对高性能聚砜中空纤维膜的未来发展方向进行预测。
Polysulfone hollow fiber membrane can be used as ultrafiltration membrane and nanofiltration membrane in water treatment,as well as hemodialysis membrane.However,polysulfone hollow fiber membrane has some disadvantages,such as poor hydrophilicity,low ultrafiltration rate and easy protein adsorption,thus it needs to be modified to improve its performance.The modification process of polysulfone hollow fiber membrane and its effects are well illustrated and analyzed in this paper.The future development directions of high-performance polysulfone hollow fiber membrane are also recommended.
