The effects of silica particles on the electric percolating behavior of the silver nanowires in the epoxy composites are elucidated using the experiments, Monte Carlo (MC) simulations and percolation theory. Many studies on nano composites, such as polymer/CNT composites or polymer/silver nano-particle composites, have been carried out to lower the volume fraction of the conducting materials at the electric percolation threshold. In this work, we elucidate that the electrical properties of the nano composites, mixtures of conductive nanoparticles and polymers, can be improved significantly by mixing the additive particles with the nano composites. When the silica particles are added to the epoxy/silver nanowire composites, the electric resistivity decreases by about eight orders of magnitude. According to the TEM images and the simulation results, the silver nanowires aggregate at low concentration of the silver nanowire due to their strong attractive interaction. However, when the silica particles are introduced the silver nanowires are dispersed well, which makes the electric percolation network of the silver nanowires form easily.
