The novel anion exchange membranes were synthesized by modified polyvinylidenefluoride (PVDF) and aminated 4-toluidine. Before aminating, 4-toluidine was brominated by N-bromosuccinimide (NBS). Anion exchange membranes were cross-linked using divinylbenzene to improve the mechanical strength. The chemical structure of PVDF anion exchange membranes were investigated by Fourier-transform infrared (FTIR) spectrometry and nuclear magnetic resonance (12C NMR). The membrane's properties such as swelling ratio (S.R), water uptake (W.U), ion exchange capacity (IEC), total dissolved solids (TDS) and electric resistance (E.R) were measured by back titration and LCR meter etc. |
