In this study, the coupling of IGC-ID analysis and carbon blacks impregnation with increasing ratios of polymer allow us to highlight the affinity of the polymer to the solid surface. The variations of the dispersive component of the surface energy and of the nanomorphology index are monitored versus the degree of carbon black impregnation. A clear correlation between the decrease in the dispersive component of the surface energy and the increase in the nanomorphological index is observed. The PBu macromolecules shield progressively the slot shaped sites on the carbon blacks surface. IGC reveals clear differences in surface properties between CB of different grades.
