Conductivity And Permittivity Of Nickel-Nanoparticle-Containing Polymer Materials In The Vicinity Of Percolation Threshold
Abstract
The behaviour of conductivity ? and permittivity ? of metal-polymer composites comprising Ni particles dispersed in the phenilon was studied. It is found that the percolation-like behaviour of ? and ?, which is observed when the Ni particles are the sizes of 1-3 µm (micro-dispersed particles), gave way to another behaviour characterized by an additional contribution to ? and ? below the percolation threshold when the Ni particles are the sizes of ? 30 nm (nanoparticles). This peculiarity of the behaviour of ? and ? of the composites can be explained in the frame of the network hierarchy model of composites, which was proposed recently by Balberg et al.Downloads
