Abstract

Analytical model of the dielectric material with embedded nanoparticles doped with conductive atom clusters containing the interphase space charges has been developed. A combined solution of the permittivity equation of the heterogeneous system with the Gauss-Codazzi and the electric potential continuity equations is allowed to simulate the relative permittivity of the composite dielectric material as a function of the concentration of the embedded nanoparticles, as well as the space charge content. The simulations for the Polytetrafluoroethylene (PTFE) dielectric material with embedded carbon nanoparticles doped with Fe atom clusters showed that the relative permittivity of the PTFE nanocomposite increases with increasing the amount of the embedded CNPs doped with Fe clusters and the charge content. In absence of embedded CNPs, the solution reduces to the Maxwell-Garnett equation.
