Synthesis and Characterization of Sulfonated Poly (arylene ether sulfone) Multiblock Copolymers containing DHTPE and BFTPB for PEMFC |
| 초록 |
Poly (arylene ether sulfone) Multiblock Copolymers containing DHTPE and BFTPB were synthesized via a coupling reaction between phenoxide-terminated hydrophilic oligomers(DHTPE and BFTPB) and fluorophenyl end-capped hydrophobic oligomers(BPS and FPS). The block length and block combination of copolymers were varied by precisely controlling the molecular weight Mn and end group functionality of oligomers. The resulting hydrophilic-hydrophobic sequenced multiblock copolymers afforded transparent, ductile, and tough membranes by solution casting from DMAc. Membrane properties of these copolymers were characterized including intrinsic viscosity, thermal stabilities, morphology, water uptake, and proton conductivity. |
