Adsorption of polyanions on nanostructured polypyrrole submonolayer grafted on semiconducting transparent support

Polypyrrole submonolayers are formed on three different supports: indium oxide (In2O3), indium tin oxide (ITO) and tin oxide (SnO2). It is seen that this formation is a function of the nature of the substrates. Nanometric film scale has been checked by AFM measurements. These polypyrrole submonolayers allowed self-assembling with polyoxometalate \( {\text{SiMo}}_{{{\text{12}}}} {\text{O}}^{{{\text{4}} - }}_{{{\text{40}}}} \) and played a determining role in the adsorption characteristics.
