Importance of Molecular Interactions in Colloidal Dispersions

Figure 10

The coefficient of friction (COF, filled circles) and the viscosity (filled squares) of a fluid made up of two opposing polymer brushes with degree of polymerization equal to 7 beads, immersed in a solvent, as functions of the grafting density of polymer chains. The error bars for the viscosity are smaller than the symbols’ size. Dotted lines are only guides for the eye.
