While commercial polystyrene-based anion exchange membranes(AEMs) have simple manufacturing processes, they also possess the poor durability due to their brittleness. Poly(ethylene glycol)methyl ether methacrylate(PEGMA) with hydrophilic side chain of poly(ethylene glycol)(PEG) was used as a co-monomer to make the membranes have improved flexibility. For the preparation of the AEMs, a porous PE substrate was immersed into monomer solutions and thermally polymerized. The prepared membranes were then subsequently post-aminated using trimethylamine(TMA). The prepared pore-filled AEMs were evaluated in terms of ion exchange capacity(IEC), electric resistance and water uptake. |
