Abstract

The results of the studies on the effect of polymer metal interaction on the structure of particulate silver films formed on softened polymer substrates are presented in this paper. Silver particulate films were deposited on three different softened polymer substrates namely, Polystyrene (PS), the poly(2-vinylpyridine) (P2VP), poly(4-vinylpyridine) (P4VP), by vacuum evaporation technique in a vacuum of 8X10-6 Torr at a constant deposition rate of 0.4 nm/sec. The in-situ electrical resistance measurements, scanning electron microscopy, optical absorption spectroscopy were performed on these films. It is found that apart from the deposition conditions, polymer-metal particle interaction plays a dominant role in determining the structure and thereby, properties of particulate silver films on softened polymers. Morphology of the film is very much sensitive to this interaction and the extent of the interaction is interpreted in terms of the presence and position of nitrogen atoms in the monomer repeat unit of the polymers.
