A new metallorganic silver precursor, Ag(hfa)tetraglyme, has been used to produce silver aggregates into polymeric thin film matrices by thermal reduction in a temperature range between 200 °C and 300 °C. Here we present a characterization of the metal aggregates into polyimide thin films (0.1–1 μm). The size of the metallic particles has been measured by transmission electron microscopy (TEM). A narrow particles size distribution centered around a radius value of ~ 16 nm has been observed. X-ray diffraction (XRD) performed on this sample confirms the presence of metallic silver. X-ray photoelectron spectroscopy (XPS) has been used to determine the elemental composition at the particle surface. A partial oxidation of the metal particles, probably due to the air contamination or to interaction with oxygen of the polymeric matrix, has been observed.
