Abstract

Electrical conductivity of open cell porous silver (Ag) with sub-micrometer features was studied. Porous Ag was formed from annealing Ag nanoparticles at 150°C up to 5 minutes. Porous Ag is a network of cylindrical ligaments joined at their ends to spherical vertices. Electrical conductivity of porous Ag was ~20% of bulk value after 5 mins annealing. Kelvin cells (truncated octahedrons) with cylindrical ligaments and spherical vertices (CLSV) were used to compute electrical conductivity which is in agreement with experimental data, without any fitting parameter. Results of the CLSV model are also in agreement with the well-established Koh-Fortini empirical relation.
