Phase separating colloid polymer mixtures in shear flow

Abstract:

We study the process of phase separation of colloid polymer mixtures in the (spinodal) two-phase region of the phase diagram in shear flow. We use a counter-rotating shear cell and image the system by means of confocal laser scanning microscopy. The system is quenched from an initially almost homogeneous state at very high (200 s-1) shear rate to a low shear rate . A spinodal decomposition pattern is observed. Initially, the characteristic length scale increases linearly with time. As the str...
