Abstract

Fractal growth of metallic silver within a polymer matrix has been induced by chemical reduction of a suitable sol. A fractal dimension of 1.73±0.01 over a length scale 100-10000 nm has been estimated. The fractal structure consists of an aggregation of nanosized silver particles having diameters of the order of 15 nm. Electrical conductivity of these nanoparticles shows a lowering of the effective Debye temperature as the particle size is reduced.
