Indholdsfortegnelse:
- <p>The behaviour of conductivity <em>σ</em> and permittivity <em>ε</em> of metal-polymer composites comprising Ni particles dispersed in the phenilon was studied. It is found that the percolation-like behaviour of <em>σ</em> and <em>ε</em>, 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 <em>σ</em> and <em>ε</em> below the percolation threshold when the Ni particles are the sizes of ≤ 30 nm (nanoparticles). This peculiarity of the behaviour of <em>σ</em> and <em>ε</em> of the composites can be explained in the frame of the network hierarchy model of composites, which was proposed recently by Balberg et al. </p>
