Electroactive properties of the multilayer films containing Prussian Blue nanoparticles

Abstract

Abstract. In our work we have focused on the incorporation of Prussian Blue nanoparticles (NP) into polyelectrolyte multilayer films (PEM). The main goal of presented studies was to obtain polymer/nanoparticles films with controlled electroactive properties. The amount and ordering of deposited nanoparticles depended on the adsorption conditions of the underlying polymer anchoring layer. In the case of fully charged polyelectrolyte layer, nanoparticles were distributed uniformly. When anchoring layer was not completely charged, strong aggregation of nanoparticles at the surface was observed, causing diminution of current response of studied nanocomposite films. Thus, the selection of the proper formation conditions of nanocomposite films may influence their properties and it may even enhance their response.
