A modified sol–gel synthesis of di-urethanosil resins provides an easy preparation of single-ion conductor membranes, by combining in one pot the in situ formation of oligosilsesquioxane nanofillers, the crosslinkingof PEO chains and the covalent grafting of anion groups. Prototypal membranes demonstrated promising combination of thermal stability, flexibility and lithium ion conductivity performance.
