| 제목 | Synthesis and characterization of sulfonated poly(arylene ether sulfone) copolymer with carboxyl group |
| 초록 | A direct methanol fuel cells (DMFCs) using polymer electrolyte membranes has gained much interest over the last decade. Most DMFC research has concentrated on polymer electrolyte membrane fuel cells (PEMFC) fed directly with methanol. Aromatic poly(arylene ether sulfone)s are well-known engineering thermoplastics that display not only excellent thermal and mechanical properties, but also high resistance to oxidation and acid catalyzed hydrolysis. In our study, sulfonated poly(arylene ether sulfone) membranes containing a carboxyl group in its side chain have been synthesized by the nucleophilic displacement reaction of 4,4’-dichlorodiphenyl sulfone, sulfonated 4-4’-dichlorodiphenyl sulfone, and phenolphthalin. Their water swelling, ion exchange capacity, proton conductivity and methanol permeability were investigated in an attempt to characterize membranes for DMFC application. The prepared proton exchange membranes at each preparation condition possessed the IEC in the range of 0.3 ~ 1.4 meq./g-dry membrane. The proton conductivity of sulfonated poly (arylene ether sulfone) membranes are in the range from 10-3 ~ 10-2 S/cm. |
