Abstract

A poly(vinylsulfonic acid) (PVSA)-grafted poly(ether ether ketone) (PEEK) was simply prepared by one-pot, γ-ray radiation-induced graft polymerization of the vinylsulfonic acid (VSA) solution dissolving PEEK. The VSA-highly-grafted PEEK membrane possessed high ion exchange capacity (e.g., 7.2 mequiv g-1) and showed proton conductivity in the order of 10 -1 and 10-3-10-6 S cm-1 under hydrated and nonhumidified conditions, respectively.
