Figure 1. Segregation observed when preparing the XS-MV4 cell
To observe the behavior of individual particles in the shear cell, an
optical microscope with a 200x magnification lens (Keyence VH-Z20R) was
positioned above the shear cell, as shown in Figure 2. The resulting
images and videos detail the motion of particles visible through the gap
between the base of the shear cell and the lid. Although this approach
does not directly capture the motion of particles within the bulk system
inside the shear cell, it does provide an understanding of particle
behavior on the free surface of the blend.
