The aminated polyketone-g-vinylbenzyl chloride anion exchange membrane was graft copolymerized using the irradiation grafting technique. The synthesis results and the morphology of the membrane were confirmed by Fourier-transform infrared(FT-IR) spectroscopy and Scanning electron microscopy-energy disperse X-ray spectrometer(SEM-EDS) analysis. Also ion exchange capacity(IEC), water uptake(W.U) and electrical resistance(E.R) of the membrane were measured by titration, gravimetric method and LCR meter respectively. The degree of grafting increased from 13.05% to 98% as the irradiation dose and the monomer concentration increased. The water uptake ranged from 11.11% to 35%. The ion-exchange capacity increased from 0.34 meq/g to 1.2 meq/g, and the electrical resistance decreased from 8.48 Ω‧cm2 to 1.4 Ω‧cm2 as degree of grafting increased. |
