Abstract

Self-consistent-field theory is used to predict the center-of-mass distribution of spherical nanoparticles embedded in the lamellar phase of a diblock copolymer melt. The calculation is performed in the dilute limit, where the particle-particle interactions have a negligible effect on the distribution. We investigate how the distribution is affected by particle radius R, surface affinity ΛN, diblock segregation 􏰇N, diblock composition f, and invariant polymerization index Nh. While the preferred location of the particles (i.e., interface or domain center) is primarily controlled by ΛN, the degree of particle localization depends on several factors. Larger values of R, 􏰇N, and Nh all tend to produce narrower particle distributions.
