摘要

利用 γ 射线共辐照技术在聚醚砜（PES）膜上接枝了甲基丙烯酸。通过改变甲基丙烯酸单体浓度，获得了具有不同接枝率的改性PES膜。研究结果表明，在单体浓度<10%的范围内，接枝率与单体浓度成线性关系，提高接枝率有助于改善聚醚砜膜的亲水性。

Abstract

Grafting methyacrylic acid onto poly(ether sulfone) membranes was realized by means of simultaneous irradiation in liquids. The modified membranes with different grafting ratios were obtained by changing the concentration of methyacrylic acid. It was shown that the grafting ratio increased lineally as the monomer concentration was less than 10% and hydrophilicity of the membranes was improved with increasing grafting ratios.
