Radiation-induced grafting of vinylbenzyl chloride onto a poly(ether ether ketone) film

In this study, the effects of various irradiation conditions including solvent, monomer concentration, total dose, and dose rate on the radiation grafting of a VBC monomer onto a PEEK aromatic hydrocarbon film for the preparation of a PVBC-grafted PEEK (PEEK-g-PVBC) film were investigated. The results show that the desired PVBC-grafted PEEK film can be prepared using a simultaneous irradiation grafting method, and that the degree of grafting (DOG) of the film is largely influenced by the irradiation conditions. Among the applied solvents, halogenated solvents, dichloromethane and chloroform, were found to be suitable for grafting. The successful preparation of the grafted film was confirmed using analytical instruments such as FT-IR, TGA, and SEM-EDX.
