Abstract (English):
Sol-gel synthesis received hybrid composites of 4-vinylpyridine/2- hydroxyethylmethacrylate/SiO2. Membranes based on these composites, followed by orthophosphoric acid doping, have a proton conductivity of 1.910-2 Sm/sm(80 C), a proton transfer activation energy of 12 ± 2 kJ/mol and an ion-exchange capacity of 1.8 mg-eg/g.
