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 nm 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.
