dc.description.abstractGrafting of styrene onto poly(vinylidenefluoride) (PVDF) and poly(tetrafluoroethylene) (PTFE) films was studied for the synthesis of ion exchange membranes. Radiation-induced grafting of styrene onto PVDF and PTFE films was investigated by simultaneous method using a Co60 source. The films of PVDF and PTFE were irradiated at total dose of 20 to 120 kGy and chemical changes were monitored after contact with styrene. Films of PTFE and PVDF were immersed in styrene/toluene 1:1 and were submitted to gamma radiation. After irradiation the samples were evaluated at periods of 0, 7, 14, 21 and 28 days, at room temperature in order to measure the grafting degree. Results of infrared spectroscopic analysis (FTIR), differential scanning calorimetry (DSC), thermogravimetry analysis (TGA) and the degree of grafting (DOG) were evaluated. The characterization techniques showed that irradiated PVDF and PTFE films exhibited a much higher grafting degree at 120 kGy.
