Method for manufacturing of high-density nano-pattern metal nanostructure and metal nanostructure thereby

摘要

The present invention relates to a method for preparing a metal nanostructure in the form of a highly integrated nanopattern, and to a metal nanostructure produced by the present invention, and more particularly, to a block copolymer comprising a hydrophilic block and a hydrophobic block in the presence of a solvent, and a first metal precursor. Applying the mixture onto a substrate to form a coating layer; Irradiating the coating layer formed in the step with ultraviolet rays to remove the block copolymer and reducing the first metal precursor to prepare a first metal nanostructure; And preparing a second metal nanostructure by reacting the first metal nanostructure prepared in the step with a second metal precursor solution having a higher standard reduction potential than the first metal. It relates to a method for producing a structure. In addition, the method of manufacturing a metal nanostructure according to the present invention is a hybrid metal nanostructure formed by combining a first metal and a second metal by partially manufacturing a second metal nanostructure on a template having a first metal nanostructure. It is possible to manufacture.
