Effects of Non-Newtonian Fluids on Banding Solution

Scarlett Singletary

My current research at Lonza involves the measurement of viscosity and electrical conductivity on various materials. Viscosity poses as a reason for concern as an identifying measure for materials given the fact that most materials that we work with are Non-Newtonian. This means that as shear stress is applied to the solution, the viscosity will change. In order to prepare various materials, the addition of shear stress to a solution is inevitable. This makes electrical conductivity a more reliable source for providing data that is constant regardless of the amount of shear stress applied. This is because electrical conductivity is based solely on the concentration of the material, unlike viscosity which is also dependent on the shear rate applied.
