    • note
    • Due to the A coating on the particles, the addition of these fillers alters the composition of the original A/B mixture. For example, in the case of 100 particles, the composition is shifted from the initial 50:50 critical mixture to a 53:47 slightly "off-critical" system. To test whether the particles or the effective off-criticality are responsible for the new morphology, we carried out simulations on a 53:47 AB blend without particles. These systems still display a bicontinuous structure. Thus, the disruption of the B network is directly due to the presence of the mobile particles, not the effective off-criticality of the mixture.

    • note
    • To emphasize that this slowing down is due to the presence of the particles and not the effective off-criticality of the mixture, we investigated the domain growth for a significantly off-critical binary mixture in the absence of particles. In particular, we focused on a 65:35 AB blend. We saw no significant deviation from the Lifshitz-Slyozov growth law over comparable times.

    • The "cutting" by the particles is not an artifact of the Kawasaki exchange dynamics. Using a model that allows for a "smoother" motion of the particles, we observe the same structure

    • note
    • Note that the mobile particles not only drift in the shear flow, but also move randomly in the system. The latter motion "cuts" the long, striped domains that are formed under the imposed advection, and thus, decreases the effect of shear on the domains. Hence, the shear rate is effectively reduced in the presence of the moving particles. We include here a smooth dependence on particle density.
