Well-organized metallic nanopatterns can be created through self-assembly of block copolymers. These metallic nanopatterns can be used as templates to achieve secondary patterns of interest. For example, due to thiol group have strong interaction with gold, alkanethiol patterns can be made. Alkanethiol patterns have potential applications range from molecular devices to biorecognition to nanotechnology. In this work, we have created metallic nanopatterns by using the self-assembled nanostructures of PS-b-P2VP block copolymers where metal ions are selectively loaded into P2VP domains via protonation of P2VP blocks for fabrication of alkanethiol nanostructures. The order and orientation of P2VP cylinders were controlled by solvent annealing. Various gold nanopatterns followed well-ordered P2VP cylinders that had been produced by block copolymer self-assembly. Along the metallic nanopatterns, highly-ordered alkanethiol nanostructures were generated well. |
