Poly(arylene ether ketone)s (PAEKs) with pendant quaternary ammonium groups were synthesized. Firstly, PAEKs containing carboxylic acid groups was activated and react with N,N-Dimethylethyleneamine. Then, quaternization and alkalinization method were used to develop the membrane. Anion conductivity were expected as an important characteristic of membrane. Nuclear magnetic resonance (1H NMR) confirms the chemical reaction for PAEKs anf PAEKs-NHS, Fourier transform infrared spectroscopy (FT-IR) will characterize the quaternary ammonium poly(arylene ether ketone)s hydroxide (QAPAEKs-OH). Differential scanning calorimetry (DSC) is used to determine thermal properties of the membranes. The anion conductivity, water uptake, ion-exchang capacity (IEC), mechanical properties of the QAPAEKs-OH membranes were mesured for applications in alkaline fuel cells. QAPAEKs-OH will promise as a nwe materials for alkaline fuel cells. |
