Effects of particle softness on shear thickening of microgel suspensions.
A series of microgel particles composed of a polystyrene (PS) core and a thermo-sensitive poly(N-isopropylacrylamide) (PNIPAM) shell with different shell thicknesses were investigated to elucidate the effect of microgel softness on its shear thickening behavior. Since the softness of the microgels increases with decreasing temperature through the volume phase transition effect of PNIPAM shell, ...
متن کاملMicromechanics of Composites with Integrated Shear Thickening Fluids
Shear thickening fluids (STFs) are typically composed of a concentrated stabilized dispersion of rigid sub-micron particles in a carrier fluid and show a marked increase in viscosity beyond a critical shear rate [1]. It has been demonstrated that STFs can be integrated in dynamically loaded structures to tailor their damping and stiffness properties [2]. Potential applications are alpine skis w...
متن کاملShear-Thickening Fluid
Shear-Thickening Fluids (STFs) are a special Non-Newtonian Fluid that act like a solid when they experience a force. A simple example of this is a mixture of cornstarch and water. In this experiment, I text this mixture’s STF properties by using a ball drop to simulate an impact. By varying the ball drop height (and thus the force upon impact), and observing the bounce height, I determined wher...
متن کاملDynamic jamming point for shear thickening suspensions.
We report on rheometry measurements to characterize the critical behavior in two model shear thickening suspensions: cornstarch in water and glass spheres in oil. The slope of the shear thickening part of the viscosity curve is found to increase dramatically with packing fraction and diverge at a critical packing fraction phi(c). The magnitude of the viscosity and the yield stress are also foun...
متن کاملShear thickening in colloidal dispersions
First of all, I will introduce the basics of Newtonian fluids, followed by differences in comparison to non-Newtonian fluids. Following that, I will consider suspensions and focus on the shear thickening phenomena. Different theories behind that lead us to an order-disorder system and a hydro-clusters formulation. Finally, I will present its applications and prospects for the future.
