The nanostructure of perfluorinated sulfonic acid (PFSA) polymers is closely related to the physicochemical properties of the membranes. However, their real nano-structural morphology is still controversial due to invisible scale with just a few nanometers. Moreover, studies on the nanostructures of the PFSA membranes have been mainly focused on the ionic domain. On this basis, here we describe the crystalline domain of the PFSA membranes as well as their ionic domain based on small angle X-ray scattering (SAXS) results. Both ionic and crystalline domains showed significant alterations during hydration, and the different behaviors based on the side chain length of the PFSA membranes are also described. The short side chain-tethered PFSA membrane showed a widespread ionic domain and lacking crystalline domain with their relatively temperature-dependent tendency compared to the flexible long side chain-tethered PFSA membrane. On this basis, the correlation between nanostructure and membrane properties is described from various perspectives |
