제목 Development of cross-linked membranes via thiol-ene click reaction using thiol-terminated sulfonated poly(arylene ether sulfone) for proton exchange membrane
초록 Thiol-terminated sulfonated poly(arylene ether sulfone) (SH-SPAES) are synthesized to fabricate end-group cross-linked structure proton exchange membrane. Acrylo-polyhedral oligomeric silsesquioxane (A-POSS) is used as a multifunctional cross-linker via thiol-ene click reaction. SH-SPAES is prepared by stepwise reactions between phenoxide-terminated SPAES and end capping reagents such as decafluorobiphenyl and thiobisbenzenethiol. The cross-linked membranes exhibit improved physicochemical properties compared with linear SPAES having degree of sulfonation for 70 mol%. Under 90 oC, 100%RH condition, the power density values at 0.5 V of MEAs for C-SPAES-10 and -20 are 1.22 and 1.09 A cm-2, respectively.
