Mechanical properties of dense suspensions: Variations with interaction potential

The influence of interparticle potential on the rheology of dense suspensions was studied experimentally. Monodisperse submicron silica particles in aqueous solutions were used as model suspensions. The interaction potential between the particles was manipulated from repulsive to attractive by adjusting the concentration of KCl and cetyllrimethylammonium bromide (CTAB) in the solutions. The normal and frictional forces between pairs of the silica particles were measured directly with an atomic force microscope (AFM). The rheology of suspensions of the particles was studied with a constant stress rheometer.
