There is a great interest in the improvement of lead dioxide based materials for use in different applications. Some metal ions present in the Pb(II) deposition solution are well incorporated into the PbO2 matrix during electrodeposition (for example Bi3+, Fe3+, F-) to produce a doped oxide with improved reactivity and stability in comparison with pure PbO2 [1-3]. In comparison, there is much less information on effects of polyelectrolytes and surfactants additives on the process of oxide electrodeposition and the physicochemical properties of the resulting materials [4-6]. In the present work we used some polyelectrolytes (Nafion, Drimax 1235, Magnafloc, gelatin, polyamino guanidinehydrochloride) and surfactants (potassium salt of nonafluoro-1-butanesulfonic acid, sodium dodecylsulphate, sodium lauretsulphate) as electrolyte additives for electrosynthesis of composite materials oxide-polyelectrolyte and oxide-surfactant.
