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. These periodic nanostructures can be aligned in specific orientation by directed self-assembly, which can be utilized as guiding templates to arrange nano-sized objects. In this study, we first fabricated cylindrical nanostructures of diblock copolymers oriented by the graphoepitaxial method. Cylindrical nanodomains were effectively aligned along the underlying topographic pattern, from which we obtained the guiding template with well-aligned nanochannels after removing the cylindrical nanodomains. Then, gold nanorods were guided by the nanotemplate and their plasmonic properties were investigated depending on their placement and orientation. |
