Diblock copolymers, consisting of two chemically distinct homopolymers linked by a covalent bond, spontaneously assemble into a variety of periodic nanostructures, of which size and morphology can be effectively adjusted in nanoscale. In addition, diblock copolymer forms nanometer-sized micelles consisting of a soluble corona and an insoluble core in a selective solvent for one block of copolymers. Thin films of diblock copolymers and their micelles can be used as nanotemplates to generate metallic nanostructures on solid substrates. In this study, we synthesized Pt nanostructures from diblock copolymers and their micelles to tailor the morphology of both reduced graphene oxide and CVD graphene. Pt nanostructures were capable of inducing catalytic reactions to remove carbon atoms to tailor graphene into desired nanostructures. The size and spacing of graphene nanostructures were effectively controlled by those of Pt nanostructures governed by molecular weights of copolymers. |
