ELECTRIC CONDUCTIVITY MODEL OF METAL-INSULATOR COMPOSITES WITH AN INTERFACIAL SHELL

An electric conductivity model of metal-insulator composites with an interfacial shell is given. And the expression for the effective electric conductivity of a metal-insulator composite with an interfacial shell is presented. Considering the interaction of metal particles, with consideration of the interface layer between two distinct topological structures, a simple self-consistent way is used to improve this expression. The theoretical results on electric conductivity of silver-phenol composites are in good agreement with experimental data.
