Abstract
| - We develop a coarse-grained model to investigate the influence of nanoscale particles onthe phase separation and the morphology of symmetric AB diblock copolymer films. The microphaseseparation is modeled by the cell dynamical systems (CDS) equations, while the particle dynamics isdescribed by the Langevin equation. We assume that the particles have a selective interaction with theA block, and we vary the interaction strength, the particle number density, and mobility. The mobileparticles destroy the bicontinuous structure that is typical for symmetric diblocks. In the limit of weakinteractions between the A blocks and particles, the A's form the continuous phase and the B's formisolated domains. In the case of strong particle/A block interactions, the B phase is continuous and theA blocks self-assemble into distinct islands. Thus, the character of the continuous phase can be tailoredby varying the strength of the block−particle interaction.
