RADIATION-INDUCED GRAFT-POLYMERIZATION OF ACRYLIC-ACID ONTO FLUORINATED POLYMERS .2. GRAFT COPOLYMER-METAL COMPLEXES OBTAINED BY RADIATION GRAFTING ONTO POLY(TETRAFLUOROETHYLENE-PERFLUOROVINYL ETHER) COPOLYMER

Radiation induced grafting of acrylic acid onto poly (tetrafluoroethylene-perfluorovinyl ether) (PFA) films was investigated. The grafted films rapidly adsorbed Fe3+, Co2+, Ni2+, and Cu2+ ions in high efficiency. The polyacrylic acid grafted onto PFA acted as a chelating site for the previously selected transition metal ions. Such prepared copolymer-metal complexes were confirmed spectrophotometrically via IR, UV-spectrometry, X-ray fluorescence, X-ray diffraction, and colour index measurements. Electrical conductivity and mechanical properties of PFA grafted copolymer-metal complexes were investigated. The applications of such prepared copolymer-metal complexes in the field of semiconductors besides its performance as a cation-exchange membrane may be of great interest.
