Key Points

To evaluate the efficacy and accuracy of five sigmoidal mathematical models in predicting the electrical conductivity percolation threshold of extrinsically conducting polymer composites compared to classical percolation theory.
Applied five sigmoidal models—Sigmoidal-Boltzmann, Sigmoidal-Dose Response, Sigmoidal-Hill, Sigmoidal-Logistic, and Sigmoidal-Logistic-1—to ethylene vinyl acetate and acrylonitrile butadiene copolymer composites filled with carbon particles.
Benchmarked model predictions against values derived from classical percolation theory and evaluated universal applicability using published experimental datasets.
The Sigmoidal-Boltzmann and Sigmoidal-Dose Response models produced nearly identical percolation threshold values for individual composite formulations, whereas the other evaluated models yielded varying estimates.
Except for the Sigmoidal-Logistic-1 model, all examined sigmoidal models successfully and reliably determined the electrical percolation threshold for extrinsically conductive polymer composite systems.
