Characterization and applications of PVF film grafted with binary mixture of methacrylic acid and 4-vinyl pyridine by gamma radiations: Effect of swift heavy ions

Graft copolymerization of a binary mixture of methacrylic acid and 4-vinyl pyridine, onto poly (vinyl fluoride) film has been carried out by preirradiation method. Under optimum reaction conditions, maximum percentage of grafting, Pg, (92.10%) was obtained. Irradiation of the film by swift heavy ions, silicon and carbon, gave maximum Pg (77.50%) for Si+8 irradiated film. Grafting of 4-VP onto PVF-g-poly (MAAc) films produced maximum Pg of 77.00%. FTIR, TGA, swelling ratio, ion and metal uptake studies were used for characterization.
