Abstract
Disclosed is a method for producing a silver-containing nanostructure which can reduce the time required for a post treatment step and the amount of a waste material and which is achieved by the application of the reduction reaction of silver oxide; and a silver-containing nanostructure having a specific structure, which can be produced by the method. Specifically disclosed is a method for producing a silver-containing nanostructure, including dispersing a polymeric compound in which a hydrophilic segment is bonded to a polyalkyleneimine chain in a medium, adding silver oxide thereto, and carrying out a reduction reaction of the silver oxide, thereby obtaining a silver-containing nanostructure. In the method, a structure having a branched structure can be produced when a specific compound is used as a complexing agent. The silver-containing nanostructure thus produced can be used as a conductive paste or the like.
