Abstract
Nanocomposite organic/inorganic materials made through sol-gel method exhibit high values of ionic conductivity when they were impregnated with the redox couple I −3 /I− Two different kinds of nanocomposite materials, depending on the different interactions between silica and poly(ethylene)oxide or poly(propylene)oxide blends, were prepared by the sol-gel technique in room temperature. Gels, for both nanocomposite materials, were obtained by acetic acid catalyzed solvolysis and were regulated by formation of intermediate products, such as silicon ester and -Si-O-Si-oligomers. Time-resolved fluorescence techniques and conductivity measurements were performed in order to define the parameters which allow maximum probe mobility and minimum confinement conditions with the aim to apply these materials in quasi solid state electrolytes.
