제목 Perfluorocyclobutyl-containing multiblock copolymer with maximized hydrophilic/hydrophobic phase separation
초록 Partially fluorinated perfluorocyclobutyl-containing hydrophobic oligomer and highly sulfonated poly(phenylene sulfide sulfone) hydrophilic oligomer were synthesized to multiblock copolymer. The well-developed hydrophilic/hydrophobic phase separation was observed in TEM image and in SAXS analysis. Membranes were thermally annealed at low temperature which led to enhanced connectivity of proton conducting channel. The adhesion strength against Nafion was 32.74 mN cm-1, suggesting strong interfacial compatibility in membrane electrode assembly. Fuel cell performance was 1.1346 A cm-2 (100% RH, 65 oC) at 0.6 V, and humidity (wet/dry) cycling test was maintained for 8080 cycles.
