摘要
采用液相共辐照技术在聚砜超滤膜上接枝丙烯酸。通过改变辐照剂量和丙烯酸单体浓度可以获得具有不同接枝率的改性聚砜膜。实验结果表明，随着接枝率的提高，改性聚砜膜抗蛋白质吸附污染的能力显著增强。并且认为接枝膜的亲水性提高是膜污染减轻的主要原因。
The grafting of acrylic acid onto polysulfone UF membranes was performed by means of mutual irradiation in liquids.And the modified membranes with different grafting rate were obtained by changing irradiation rate and concentration of acrylic acid.It was shown that the modified membranes with higher grafting rate expressed better anti-fouling ability in the ultrafiltration of protein solutions.The reason for this was mainly because increasing of hydrophilicity with grafting rate.
