In this study, a method to generate arrays of Fe3O4 nanoparticles (MNPs) via block copolymer (BC) self-assembly was developed. A composite film of polystyrene-block-poly (2-vinylpyridine) (PS-b-P2VP)/MNPs was first prepared by spin-coating the PS-b-P2VP/MNPs mixed solution on a carbon substrate. After the composite film was annealed at high temperature for 2 days, it was found that the modified MNPs could be selectively incorporated into P2VP cylinders in PS-b-P2VP diblock copolymers and the P2VP cylinders were oriented parallel to the substrate. For a long time annealing (10 days), the P2VP cylinders become normal to the substrate and MNPs are located at the interface of P2VP and PS phases.

Block copolymers bearing carbazole moieties in thin films nicely demonstrated vertical or horizontal lamellar structure depending on the process condition. The vertical lamellar structure revealed permanent memory behavior, where the horizontal lamellar structure exhibited volatile memory behavior.
