Diblock copolymers, consisting of two chemically different homopolymers linked by a covalent bond, spontaneously assemble into a variety of periodic nanostructures, of which size and morphology can be effectively controlled in nanoscale. In particular, diblock copolymers can form well-aligned ordered nanostructures in lithographically patterned substrates. This directed self-assembly of diblock copolymers can be used to fabricate arrays of periodic nanostructures of various materials with controlled arrangement. In this study, we synthesized ordered arrays of nanostructures of metals and oxides from directed self-assemblies of diblock copolymers which were employed for tailoring reduced graphene oxides into desired nanostructures or for fabricating ordered complex nanostructures. The size and morphology of nanostructures were controlled by the molecular weights of copolymers and the dimensions of topographical patterns. |
