제목 Tunable and Transferable Arrays of Au Nanoparticles on Reduced Graphene Oxides
초록 Diblock copolymers composed of two different polymers spontaneously assemble into periodic nanostructures, of which the size and morphology can be controlled by the molecular weight and composition of copolymers. In a selective solvent for one of the blocks of diblock copolymers, nanometer-sized micelles consisting of a soluble corona and an insoluble core are formed. The diblock copolymers and their micelles can be coated on solid substrates to form nanostructured thin films, which can be used as nanotemplates to generate arrays of inorganic nanomaterials. In this study, we applied the diblock copolymer approach to fabricate arrays of Au nanoparticles on reduced graphene oxides, which are tunable in the size and the number density and transferable to any other substrate. We also demonstrated that the decoration of reduced graphene oxide with Au nanoparticles contributes to the enhancement in electrocatalytic activities.
