Azide-assisted crosslinked sulfonated poly(ether sulfone)s as stable and highly conductive membranes with low methanol diffusion coefficient |
| 초록 |
We have prepared crosslinked sulfonated poly(ether sulfone)s (PESs) by thermal irradiation of the allyl-terminated PESs using an azide. Having both the uniform distribution of the hydrophilic conductive sites and controlled hydrophobic nature by minimized crosslinking over the rigid rod poly(ether sulfone) backbone, our crosslinked polymer (PES-60) membrane offered high proton conductivity at high temperature without loss of the structural integrity. In addition, much lower methanol permeability than Nafion was observed. We believe these preliminary results have proved its potential availability as an electrolyte for both high temperature PEMFC and DMFC. |
