Characterization of Anion Exchange Membrane for the Application of Energy Application

In the energy field, the anion exchange membrane are emerging as trends. The anion exchange membrane should have high electrochemical and mechanical properties. The poly(ether ether ketone) (PEEK) based copolymer containing imidazolium group was synthesized by using condensation polymerization method. The synthesized PEEK had different contents of imidazolium group. For preparing the PEEK membranes, the various PEEK containing imidazolium group were dissolved in n-methyl-2-pyrrolidone (NMP). The anion exchange membrane was taken out and the solvent was volatilized on a glass plate. After the membrane was prepared, the properties of the membrane were evaluated. The ion exchange capacity was measured by back-titration method and the ion conductivity was calculated by membrane resistance method. In addition, the morphology was checked by using FE-SEM. The TGA and UTM were used to investigate the thermal and mechanical properties of the composite membrane.
