电子束共辐照接枝改性聚醚砜微孔膜
Graft-copolymerization of polyethersulfone microporous membrane with electron beam simultaneous irradiation method
【摘要】 用电子束共辐照技术在聚醚砜微孔膜上接枝了甲基丙烯酸。改变接枝单体的浓度和吸收剂量获得具有不同接枝率的改性聚醚砜膜。系统研究了接枝率与单体浓度和吸收剂量间的关系,得到最佳的单体浓度和吸收剂量。接枝膜用傅里叶红外光谱仪(FT-IR)进行表征,接枝膜表面及断面形态用扫描电子显微镜(SEM)观察,并测试了接枝膜的亲水性接触角。
【Abstract】 Polyethersulfone(PES) microporous membrane was grafted with methacryhc acid under electron beam irradiation.Controlling the monomer concentration or the absorbed dose,the relationships of the degree of grafting with the monomer concentration and the absorbed dose were obtained for optimum the monomer concentration and absorbed dose.The grafted membrane was characterized by FT-IR and SEM,and the hydrophihcity contact angle of the membrane was tested.
