Colloidal Silver Films on Polypropylene and Polyethylene

Abstract : A simple procedure for the fabrication of colloidal silver films on the surface of flexible polymer substrates, such as polypropylene and polyethylene, with the use of only polyelectrolyte pre‐treatment is presented. The optical properties of these films depend on the number of predeposited polyelectrolyte layers and salt concentration. The uncharged nature of the polymer surface allows to alternate the first polyelectrolyte layer (positively or negatively charged). The proposed method of silver deposition can be used for manufacturing silver films of different density on the polymer surfaces. This approach is low‐cost, does not require special equipment and allows to control the surface properties of the films. Using an average salt concentration (0.5 M) during the deposition of polyelectrolytes allowed to produce the densest films.
