    • At the size scales studied here, our SCF/DFT calculations show that there is no significant difference in the behavior of cubic and spherical particles when they are added to bulk diblocks. Our motivation for focusing on cubic particles is that the density functional theory for these fillers can be readily extended to parallelepipeds, and thus, we can investigate the effect of varying the particles' aspect ratio on the structure of the films. We also note that, in previous studies on the bulk properties of diblock/particle mixtures, we compared our findings from Monte Carlo simulations with cubic particles to scaling theory with spherical particles and found that cubes and spheres of comparable sizes yield qualitatively similar behavior with regard to the structure of the system.

    • In this scaling theory, we do not take into account the swelling of lamellar period in the particle-filled layers relative to the unfilled layers as the changes in the lamellar period are minor. We have observed in our SCF/DFT calculations approximately 4% degrease in the lamellar period with the addition of neutral fillers. Here, particles localized at the A/B interfaces act as compatibilizers.
