Radiation induced grafting of acrylic acid onto polyethylene film was investigated. The grafted films rapidly adsorbed Cu 2ϩ , Cd 2ϩ , Th 4ϩ , and UO 2 2ϩ ions in high efficiency. The carboxylic acid groups on AAc-grafted PE film acted as a chelating site for the selected metal ions. Complex formation of metal ions and carboxylic acid group on PE film were investigated by IR, UV/VIS and x-ray photoelectrons spectroscopy (XPS). Electrical conductivity and thermal properties of the graft copolymer-metal complexes onto PE film were also investigated. The application of such prepared graft copolymer-metal complexes in the field of semiconductor may be interest.
