The novel partialy florinated PVDF-g-VBC anion exchange membranes were synthesized by dehydroflorination of PVDF. The anion exchange membranes were prepared by casting and annealing methods. The chemical structure of anion exchange membranes were investigated by Raman spectrometry, Fourier-transform infrared (FTIR) spectrometer. The membrane's properties, such as water uptake(W.U), ion exchange capacity (IEC) and electric resistance (E.R) were measured by gravimatry, titration and LCR meter, respectively. The IEC , electrical resistance, and water uptake were 1.31 meq/g, 2.0 Ω·㎠ 56.2 %, respectively |
