Nanostructures of inorganic materials have been widely studied as promising candidates for various applications including sensors, solar cells, electrodes, and semiconductors. As an effective method for generating nanostructures over large areas, nanostructures of block copolymers have been intensively investigated because they self-assemble into periodic nanostructures, of which the size and morphology can be controlled by the molecular weight and composition of copolymers. In this study, we first employed thin films of diblock copolymers with cylindrical nanodomains to fabricate linear metal nanostructures, of which the spacing was controlled by adjusting the molecular weight of copolymers. In addition, we fabricated hexagonal arrays of metal and oxide nanodots from diblock copolymer micelles containing precursors of nanodots. In this case, the spacing between nanodots was effectively changed by controlling the coating condition of copolymer micelles. |
