Fabrication of metallized nanowires from self-assembled diblock copolymer templates

Nanowires of diblock copolymer have been prepared from separated columnar phases of a polymeric complex. Cylindrical structures are formed and oriented by oscillatory shear forces, from which nanowires several micrometers long and 30-35 mn in diameter can be extracted. These nanowires can be used as templates for both metallization with Pd (see Figure), Au, or Ni, or for adsorption of CdSe nanoparticles.
