Synthesis of Anion Exchange Membranes Containing PVDF/PES and Either PEI or Fumion^®.

ABSTRACT: In this work, the preparation of dense blended membranes, from blends of poly(vinylidene fluoride) (PVDF), poly(ether sulfone) (PES) and polyethyleneimine (PEI) or Fumion^®, with possible applications in alkaline fuel cell (AEMFC) is reported. The blended PEI/Fumion^® membranes were prepared under a controlled air atmosphere by a solvent evaporation method, and were characterized regarding water uptake, swelling ratio, thermogravimetric analysis (TGA), infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), ion exchange capacity (IEC), OH^- conductivity and novel hydroxide ion exchange rate (HIER), which is related to the mass transport capacity of the OH^- ions through the membrane. The effect of the chemical composition on its morphologi
