Abstract
The research uses a novel approach to tackle structuring in liquids through shear-gel technology, resulting in advanced material properties.
Highlights
The use of particulates as rheological modi ers spans across multiple industries: paint, cosmetic, food etc
Mechanical shear was applied to an aqueous solution of whey protein isolate (WPI) and oil heated through the sol–gel transition
The result was packing fractions that exceeded those for hard spheres (>0.64), leading to pseudo-solid characteristics at rest, apparent yield stresses and thixotropic behaviour under shear
Summary
The use of particulates as rheological modi ers spans across multiple industries: paint, cosmetic, food etc. For this reason, systems such as colloidal suspensions and emulsions have been well documented. The deformability of such so hydrogel particles led to volume fractions that exceeded those typical for hard spheres. At such high volume fractions particles become sterically con ned, rheology became more closely governed by the particle moduli.[7,8,9]
