Shear-induced structural changes in complex fluids of anisotropic species are a very general problem encountered not only in polymer solutions 1 but also in liquid crystalline materials, 2,3 block copolymer melts, 1,4,5 and platelike clay suspensions. u6

Shear Orientation of a Visoelastic Polymer-Clay Solution

August 1, 2000

Author(s)

G Schmidt, A Nakatani, Paul Butler, Alamgir Karim, Charles C. Han

The shear orientation of viscoelastic clay-polymer solutions was investigated by means of rheology, flow birefringence (δn) and small-angle neutron scattering (SANS). Oscillatory shear showed a linear viscoelastic region and flow occured at higher stresses
