Abstract

In this paper, a composite material model with ellipsoidal conductive particles was used to establish an effective conductivity model for studying graphene quantum dots (GQDs) solution. By comparing effective media theoretical (EMT) model, porous flow theory model and the general effective model (GEM), we finally selected the general effective model (GEM) to fit the concentration dependence of the effective conductivity of the GQDs. This model perfectly explained our experimental data. The GEM model is able to predict the effective conductivity of GQDs solution. On the other hand, we modified the tunnel conductivity model based on the analysis about the tunnel conductivity model and Arrhenius equation. The modified model well simulated the temperature dependence of the effective conductivity of GQDs solution and provided a more reliable guidance for the design and optimization of the GQDs composites.
