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 SiMo12O4 40 and played a determining role in the adsorption characteristics.
