采用γ射线辐照制备了丙烯酸（AAc）接枝聚对苯二甲酸乙二醇酯（PET）薄膜。扫描电子显微镜（SEM）图像显示，由于接枝链结构紧凑，接枝膜几乎没有金属离子吸附，这限制了金属离子与官能团的接触。因此，通过KOH处理对接枝膜进行改性，以扩展接枝链，以促进金属离子与官能团的接触。改性薄膜用于研究选择性 Cu2+
Acrylic acid (AAc) grafted polyethylene terephthalate (PET) films were prepared by γ irradiation. The graft films showed little metal ion adsorption due to compact structure of the graft chains as shown by the scanning electron microscopy (SEM) images which restricted the access of metal ions to the functional groups. Therefore, the graft films were modified with KOH treatment for expansion of the graft chains to facilitate the access of metal ions to the functional groups. The modified films were used to study the selective Cu2
