Rheological Properties of Non-Aqueous Suspensions of Titanium Dioxides Stabilized with Lecithin
It is well known that the flocculated suspensions show thixotropic and rheopectic flow as well as shear-thinning and shear-thickening flow. These types of time-dependent, non-Newtonian behavior are usually attributed to the structural breakdown or rebuildup within a suspension under shear. The objective of this study is to discuss the mechanism of the shear-thinning behavior observed for non-aqueous suspensions of titanium dioxides stabilized with different amounts of lecithin.
