Viscosity of CNT-dispersed polymer is predicted based on elasticity-based analogy. Micromechanical Mori-Tanaka approach is applied for the prediction of viscosity, and it is concluded that the elasticity-based model fits well with the experimental data. In addition, a semi-empirical model for non-Newtonian viscosity of CNT-dispersed polymer is proposed, and the predictions are verified with experimental results.
