Alkali-resistant metal-based cationic polyelectrolytes are developed as anion exchange membranes by grafting aminocobaltocene hexafluorophosphates onto partially fluorinated ether-free poly(arylene-alkane)s via nucleophilic substitution reaction. The membrane shows excellent chemical, thermal, and mechanical stability, high hydroxide conductivity, and durability of single cells for 400 hours.
Alkali-resistant metal-based cationic polyelectrolytes are designed as anion exchange membranes. After grafting aminocobaltocene hexafluorophosphates onto partially fluorinated ether-free poly(arylene-alkane)s via a simple nucleophilic substitution reaction, the membrane exhibits excellent chemical, thermal and mechanical stability, high hydroxide conductivity, as well as durability of single cells for 400 h.
