摘要: Using a mixture of different types fillers has been experimentally shown to improve the electrical conductivity polymer nanocomposites beyond weighted average due synergistic effects. In this study, we develop critical path analysis-based tunneling-percolation model for multicomponent systems with ellipsoidal fillers. The nature interaction between filler components is controlled by key modeling parameter capturing tunneling interactions This generalization allows us examine scenarios where given type can be varied continuously from an insulating-type conductive-type. percolation behavior two-component combination prolate, oblate, and spherical investigated using Monte Carlo simulations relative volume fractions while keeping total fraction fixed. simulation results are in semi-quantitative agreeme...
