Proton conducting borosiloxane–poly(ether-sulfone) composite electrolyte

Proton conducting polymer composite membranes were prepared by casting method from borosiloxane electrolyte containing sulfonic acid groups and partially sulfonated poly(ether-sulfone) (SPES). Proton conductivity of the composite membranes exhibited high ionic conductivity, stability to oxidation, a...

Zusammenfassung:	Proton conducting polymer composite membranes were prepared by casting method from borosiloxane electrolyte containing sulfonic acid groups and partially sulfonated poly(ether-sulfone) (SPES). Proton conductivity of the composite membranes exhibited high ionic conductivity, stability to oxidation, and good film forming ability. Silica coating on the composite membrane improved water resistance.
