METAL NANONETWORK AND METHOD FOR PRODUCING THE SAME, AND CONDUCTIVE FILM AND CONDUCTIVE SUBSTRATE USING METAL NANONETWORK

摘要

A metal nanonetwork includes metal nanostructures that are joined by metallic bond. The joined part between the metal nanostructures includes a fillet part. In the joined part between the metal nanostructures, the distance between the central axis of one metal nanostructure and the central axis of another metal nanostructure is smaller than the sum of the radii of both metal nanostructures. The metal nanostructure is a metal nanowire. A first method for producing the metal nanonetwork includes a process of forming an oxide film on the outermost surface of the metal nanostructure, and a process of reducing the oxide film at the joined parts of a plurality of the metal nanostructures to thereby join the metal nanostructures.
