Abstract:
A proton conductive graft polymer comprises at least a structure unit of a sulfonated polymer side chain covalently attached to a hydrophobic perfluorocyclobutane polymer main chain. The sulfonated condensation polymer side chain has a high local ion exchange capacity while the main polymer chain is substantially free of sulfonic acid group. A membrane made from the graft polymer can provide good mechanical properties and high proton conductivity at wide range of humidity and temperatures.
