Shear-thickening in aqueous surfactant-associative thickener mixtures
Journal of Coatings Technology and Research, 2011Associative thickeners represent an important class of rheology modifiers used in waterborne coatings. Understanding molecular level interactions between associative thickeners and surfactants has been the subject of a number of prior studies. Our recent studies focused on the behavior of a hydrophobically modified, aminoplast ether (HEAT) associative ...

Dense non-Brownian suspension has rich rheology and is hard to understand, especially for distinguishing continuous shear thickening (CST) from discontinuous shear thickening (DST). By studying the shear stress dependent rheology of a well-known DST suspension of cornstarch in water, we find that the transition from CST to DST could occur not only by ...

Shear thickening in colloidal dispersions
AIP Conference Proceedings, 1999We present a simplified model of shear thickening in concentrated colloids. The key idea of the model is that the trajectories of close approaching particles be simultaneously consistent with both the stress and the shear rate of the suspension. The weak shear thickening of Brownian hard spheres is reproduced.

Shear thinning and thickening rheology
Journal of Colloid and Interface Science, 1977Abstract Particles with radii 21–1010 nm, of methyl methacrylate homopolymer or copolymers with ethyl acrylate, were dispersed in high-boiling hydrocarbons. The stabilizer contained poly(12-hydroxystearic) acid. Viscosities at shear rates of 1–104 sec−1 were measured with cone and plate (Weissenberg rheogoniometer), becoming steady almost ...
