Abstract: The structures of a nanoparticle/copolymer mixed system were studied using lattice dynamic Monte Carlo simulations. Each copolymer chain consisted of one A bead and three B beads, and the amphiphilic property of the A1B3 chains was represented by an attraction between B-B beads. Nanoparticles were hydrophobic with an attraction amongst themselves. By properly choosing the attraction between the nanoparticle and the B beads, we observe two interesting structures: a nanoparticle/ A1B3 chain core-shell structure and an A1B3 vesicle with nanoparticles dispersed in the hydrophobic shell. The evolutions of these two structures were investigated. Our results show that the A1B3 vesicle acts as a template for the formation of the nanoparticle-dispersed vesicle.
