“…When using vapor phase deposition techniques (such as evaporation or sputtering) to growth metal NPs or films on polymeric surfaces, noble metals like Au and Ag grow, during the initial stage, as spherical clusters on polymer surfaces [13,[21][22][23][24][25][26][27][28][29][30][31][32], i.e., according to a Volmer-Weber [33] growth mode. This is due to a higher (two orders of magnitude) cohesive energy of metals with respect to the polymers' cohesive energy.…”

“…This is due to a higher (two orders of magnitude) cohesive energy of metals with respect to the polymers' cohesive energy. Moreover, the interaction between noble metals and polymers is very weak compared to the metal-metal binding forces [5][6][7][8][30][31][32]. So, noble metals do not wet, in general, polymer surfaces.…”

Abstract:In this review, we discuss the basic concepts related to (co-)evaporation and (co)sputtering based fabrication methods and the electrical properties of polymer-metal nanocomposite films. Within the organic-inorganic hybrid nanocomposites research framework, the field related to metal-polymer nanocomposites is attracting much interest. In fact, it is opening pathways for engineering flexible composites that exhibit advantageous electrical, optical, or mechanical properties. The metal-polymer nanocomposites research field is, now, a wide, complex, and important part of the nanotechnology revolution. So, with this review we aim, starting from the discussion of specific cases, to focus our attention on the basic microscopic mechanisms and processes and the general concepts suitable for the interpretation of material properties and structure-property correlations. The review aims, in addition, to provide a comprehensive schematization of the main technological applications currently in development worldwide.

“…Information related to the mechanism of the process and/or the fate of the reduced products (especially whether or not cluster formation or nucleation also take place) are needed. From this aspect XPS is particularly suitable since a significant chemical shift develops to correlate with the size of gold clusters [37][38][39][40][41][42][43][44][45][46]. Accordingly, we have recently reported an XPS investigation of HAuCl 4 deposited on SiO 2 /Si substrate and in PMMA matrix where we have demonstrated the formation of gold nanoclusters by X-ray induced reduction [47].…”

Prolonged exposure to X-rays of HAuCl 4 , PtCl 4 and their mixtures, deposited from an aqueous solution onto a silicon substrate, causes chemical reduction of the metal ions to their metallic states. The corresponding oxidation reaction is the conversion of chloride ions to chlorine. The resultant metal atoms aggregate to form metallic/bimetallic nanoclusters as evidenced from their XPS chemical shifts. Hence, X-rays are usable for in-situ nanoparticle production or for direct-writing applications on silicon substrates.

“…A further simplification was the assumption of complete condensation of metal atoms on the polymer surface. In reality, metal atoms will have a finited probability of beeing reemitted [14] after they spent some time at the surface. Since reemission is dominant for monomers though, we expect that omission of evaporation does not change the discussed quantities qualitatively but rather leads to a rescaling of the deposition rate.…”

“…First, we will not consider cluster growth and charging effects in the plasma phase but will assume a given steady and homogeneous flow of atoms onto the surface. Further, no evaporation of atoms and clusters from the surface [14] is included.…”

Nobel metals that are deposited on a polymer surface exhibit surface diffusion and diffusion into the bulk. At the same time the metal atoms tend to form clusters because their cohesive energy is about two orders of magnitude higher than the cohesive energy of polymers. To selfconsistently simulate these coupled processes, we present in this paper a Kinetic Monte Carlo approach. Using a simple model with diffusion coefficients taken as input parameters allows us to perform a systematic study of the behavior of a large ensemble of metal atoms on a polymer surface eventually leading to polymer nanocomposites. Special emphasis is placed on the cluster growth, cluster size distribution and the penetration of clusters into the substrate. We also study the influence of surface defects and analyze how the properties of the resulting material can be controlled by variation of the deposition rate.
