【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。更多还原

【Abstract】 Grafting methyacrylic acid onto poly(ether sulfone) membranes was realized by means of simultane- ous irradiation in liquids. The modified membranes with different grafting ratios were obtained by changing the con- centration 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.更多还原
