発明の名称 (英語) METHOD FOR PREPARING A SUBSTRATE WITH MICROMETALLIC MASSES ALIGNED ON THE SURFACE
発明の概要(英語)

A metallic nanostructure comprising a substrate and arranged on a surface thereof zerovalent-metal lumps having a regulated size and shape

and a process for producing the nanostructure. A micro-domain film comprising an amphipathic block copolymer can have a structure having many hydrophilic cylinders with a microfine diameter which extend within the film in the direction perpendicular to the film surfaces. An amphipathic block copolymer and a solution containing desired metal ions are used to form the film. Alternatively, a micro-domain film of an amphipathic block copolymer is formed and then brought into contact with a solution containing metal ions. Thus, the metal ions localize in the hydrophilic cylinders having a microfine diameter.

This micro-domain film is subjected to a treatment for reduction and organic-substance removal, whereby a substrate can be obtained which has formed thereon many zerovalent-metal lumps of a nearly columnar or nearly spherical shape or shapes comprising a combination of these, the lumps being arranged at regular intervals. The treatment may be irradiation with ultraviolet or electronic beams, plasma treatment, chemical reduction, or electrochemical reduction.
