Influence of Crosslink on the Transport Properties of Proton Exchange Membranes |
| 초록 |
Highly sulfonated-fluorinated poly(arylene ether) was synthesized via nucleophilic aromatic substitution. The synthesized polymer with alternatively hydrophilic and hydrophobic component in repeating unit of the polymer possessed high molecular weights and good film-forming capability for transparent and flexible membranes. The polymer exhibited excellent oxidative and dimensional stability due to the highly fluorinated aromatic main chain. Thermal properties of the polymer membranes were characterized by DSC and TGA. The proton conductivity, water uptake and swelling ratio of membranes was observed as changing the crosslinking time. |
