The viscosity behavior of suspensions flocculated by bridging was examined as a function of adsorption affinity of polymers for the particle surface. The polymer chains having strong affinity form fragile bridges between particles as a result of irreversible adsorption. Because the flocs are broken

A polymer coil with weak affinity for the solid surface makes a flexible bridge between particles by reversible adsorption. When the coil size is comparable to particle diameter in solution, the suspensions flocculated by reversible bridging show shear-thickening flow in a narrow range of shear rate
The suspension rheology of hematite in the ionic liquid Ecoeng TM. 212 was studied in detail and compared to the pure ionic liquid. This is the first report on the rheological behavior of suspensions in ionic liquids, and it is postulated that colloidal stability and rheology must be considered to u
Fumed silica was surface treated by hexyl (C6), octyl (C8), decyl (C10), hexadecyl (C16), and octadecyl(C18)trimethoxysilanes, and the products were evaluated from various aspects. The amounts of alkyl group introduced on silica surface were all within the range from 22 to 25 mmol/100 g. Such fumed
