ELECTRICAL CONDUCTIVITY OF COMPOSITE POLYMER MATERIALS BASED ON POLYETHYLENE CONTAINING COPPER NANOPARTICLES
Two types of composite materials containing micro- and nanoparticles of copper in a polyethylene matrix were developed and studied. Transmission electron microscopy revealed that the size of the formed nanoparticles is 13 nm, while X-ray phase analysis indicated that the copper nanoparticles have a "core-shell" structure. The conductivity of polyethylene containing nano- and microparticles of copper was measured near the percolation threshold. It was found that below this threshold, discrepancies between experimental data and predictions of modern heterogeneous system theory were observed. Additionally, in polyethylene-based composites with copper nanoparticles, an extra contribution to electrical conductivity was detected in the sub-threshold region. The causes of this effect were analyzed considering the spatial structure of the material within the framework of the model proposed by Balberg and his co-authors for composite systems
