This presentation reports theoretical predictions for distribution of nanoparticles in the lamellar structures of symmetric block copolymers in the framework of the polymer density functional theory and the potential

distribution theorem. We will examine all important factors in controlling the composite morphology including not only the particle size and surface energy but also the inhomogeneity of the microdomain interfaces, polymer chain length, and the system compressibility. The results will be compared with those from alternative approaches and with experimental or simulation data.
