Abstract:
Preparation of nanocomposite film structures based on citric acid and silver nanoparticles by active gas phase deposition and a heat treatment of the obtained coatings is discussed. It is shown, that the electron beam exposure of the citric acid polymer with silver nitrate leads to deposition of coating with significant amount of the initial salt, which acts as the source of clusters and the metal nanoparticles during the heat treatment. High activity of a thin citric acid layer is characteristic only of the silver layer. With respect to the inorganic salts, characterized by a high melting temperature, in particular silver chloride, the organic citric acid thin layers are inactive. This is due to the presence of significant amounts of the initiall salt in the deposited layers and chlorine metal adsorbed at the surface, which promotes the disappearance of the silver nanoparticles in the nanocomposite.
