Title:
METAL NANONETWORK AND METHOD FOR PRODUCING SAME, AND CONDUCTIVE FILM AND CONDUCTIVE SUBSTRATE USING METAL NANONETWORK
Document Type and Number:
WIPO Patent Application WO/2013/137018
Kind Code:
A1
Abstract:
The purpose of the present invention is to obtain a metal nanonetwork having a plurality of metal nanostructures, such as metal nanowires and metal nanodendrites, that are firmly connected by metal bonds, and having good conductivity at connection points. A metal nanonetwork (1), characterized in that metal nanostructures are joined by metal bonds and the metal nanostructures are metal nanowires (3), is used as a solution. The metal nanonetwork (1) is further characterized by: having fillets (6) at a joining location (5) between the metal nanostructures; and having joining locations (5) on the metal nanostructures wherein the distance between the central axis of one of the metal nanostructures and the central axis of the other metal nanostructure is less than the total value of the radiuses of both of the metal nanostructures. A first method for producing the metal nanonetwork (1) is characterized by being provided with: a step in which an oxide film is formed on at least the outermost surface of a metal nanostructure; and a step in which the oxide coating of a contact point between the plurality of metal nanostructures is reduced, and the metal nanostructures are joined to each other.
