Abstract
An overview of the most correct mathematical models for describing the thermal conductivity of polymer-carbon nanotube systems, which characterize percolation behavior, is given. It is shown that the Landauer model, which does not take into account the presence of a percolation transition at low filler concentrations, is in poor agreement with the experiment. The sigmoidal model describes experimental data well, but is purely empirical. Zhang's model turned out to be incorrect for this type of system, as it was designed for a system with a high filler content. The scaling model showed good agreement with experimental data for a system with a low percolation threshold.
