Modeling of dielectric to metal conduction transition in nanocomposites, by using high voltage discharge

摘要

Paper presents metod of the percolation phenomenon visualization through modeling metal-dielectric type nanocomposite. Model was based on high voltage discharge in air between metallic discs modeling the metallic phase. A research station for visualization and simultaneous registration of percolation process was developed and built. Models have been executed in 2 dimension plane of randomly arranged metallic discs. The quantity of metal rings models different value of metal ,.nanoparticles" concentration. For different concentration of „ nanoparticles" relationship of discharge voltage to metal concentration was determined.
