Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Imidazolium surface functionalized SiO₂ (Im‐SiO₂) nanoparticle doped proton conducting membranes were prepared for anhydrous proton exchange membrane applications. The hybrid membranes were synthesized <italic>via in situ</italic> cross‐linking of a mixture containing polymerizable oil (styrene, acrylonitrile, and divinylbenzene), protic ionic liquids (PILs), and 1‐methyl‐3‐[(triethoxysilyl)propyl] imidazolium chloride surface functionalized silica nanoparticles. The resultant hybrid membranes show proton conductivity up to the order of 10^–2 S cm^–1 at 160 °C, which is higher that of the plain membrane (10^–3 S cm^–1 at 160 °C). In addition, incorporation of Im‐SiO₂ nanoparticles could effectively prevent the release of PIL component from the composite membranes.</p> </abstract>
