Sulfonated Poly(aryl ether ketone) Membranes Containing Poly(ether benzoxazole) for Fuel Cell Applications |
| 초록 |
Novel sulfonated poly(aryl ether ketone)s containing poly(ether benzoxazole) segments (S-PAEKBO) were synthesized by the nucleophilic polycondensation for proton exchange polymer membranes. All the copolymers exhibited excellent solubility in several organic solvents, and excellent flexibility and processability. The resulting proton exchange membranes showed outstanding thermal stability even at 340 oC in air. Proton conductivities of the membranes were from 1.10 *10-2-5.50 10-2 S/cm at 80 oC and 95% RH, and 0.76*10-2-4.42*10-2 S/cm at 120 oC under water free condition. The S-PAEKBO membranes are quite promising materials for high temperature PEMFC applications. |
