摘　　要：采用低温等离子体处理技术将丙烯酰胺(AM)接枝到聚对苯二甲酸乙二醇酯(PET)静电纺丝膜上,实现了对PET纳米纤维膜的表面改性。用电子扫描显微镜(SEM)观察了纤维的形貌,红外(FT-IR)分析了纤维膜改性前后表面性质,通过铜离子吸附试验考察了纤维改性膜对Cu2+的吸附效果。结果表明:成功的将PET纳米纤维膜表面接枝上了AM,且该膜吸附水溶液中的Cu2+效果显著,适用于水中Cu2+的去除。The PET nanofibrous membrane were fabricated by electrospinning, and then grafted with AM on the surface. The morphologies of the nanofiber were characterized by SEM, meanwhile, the surface property was measured by FT IR,and the Cu^2＋ adsorption experiment investigated the adsorption capacity of the membrane. The results showed that AM had successfully grafted on the membrane （PET-g-PAM）,and the membranes exhibited high metal ion adsorption capacity. The membrane was very suitable for removing Cu^2＋ in water.
