The structural (fractal) model, applied earlier for polymer solutions, was used for description of viscosity of aqueous suspensions of carbon nanotubes. The indicated model treates adequately the dependence of suspension viscosity on concentration of carbon nanotubes. At reaching of percolation theshold of this nanofiller a sharp growth of viscosity of aqueous suspensions is observed. The model reflects adequately also the dependence of viscosity on geometry of carbon nanotubes. A knowledge of nanofiller structure, characterizing by its fractal dimension, allows to predict reinforcement degree of solid-state polymer nanocomposites.
