NANOSTRUCTURED 'BRUSH-TYPE' THIN-FILM COVERED WITH A SILVER LAYER

It was demonstrated the feasibility of a polyvinylformaldehyde nanostructured 'brush-type'thin-film covered with a silver layer. The poly-vinyl-formaldehyde nanostructured thin-film was prepared using the template deposition technique on anodic aluminium oxide film, which allowed the control of the thickness and the structure of the polymeric film. By chemical and evaporation techniques a silver thin layer was deposited on the film surface. The determination of the optical properties in correlation with the thickness was done. X-ray and electronic microscopy microstructural investigations were performed for the plastic thin-film with and without silver thin layer. The data were correlated with the specimen preparation methods.
