Thin-film nanocomposites, consisting of silver nanoparticles embedded in a dielectric fluoropolymer matrix (poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene]), were synthesized using vapor-phase co-deposition. The electrical conductivity of these composites was measured in-situ as a function of film thickness at various metal concentrations. At low metal concentrations (< 30%), dielectric behavior and very little change with film thickness were observed. At moderate to high silver loadings (30-80%) a large increase in electrical conductivity was observed as the films grew thicket. As the thickness increased further, the conductivity flattened out. At very high silver content (> 90%), fragmented fractal nanoclusters were able to further interconnect to achieve the percolation process and eventually evolve into a metallic continuum with dielectric polymer inclusions.
