Discontinuous Shear Thickening (DST) transition with spherical iron particles coated by adsorbed brush polymer

Georges Bossis, Yan Grasselli, Olga Volkova

In this work we explore the rheology of very concentrated (0.55<$\Phi$<0.67) suspensions of carbonyl iron (CI) particles coated by a small polymer. A strong DST is observed in a large…
