Proton transport properties. a Proton diffusion coefficients, b ionic conductivities, obtained for PSS:Im-b-PMB comprising additives, measured at different temperatures. In a and b the role of ionic crystals in determining the ion transport properties of single-ion polymers was clearly shown. c Schematics depicting dominant proton hopping mechanisms in PSS:Im-b-PMB containing ZImS/Im
