  • Publication number: 20190172603
    Abstract: The present invention relates to silver-coated copper nanowires having a core-shell structure using chemical reduction and a method of preparing the same. More particularly, the present invention relates to a method of preparing silver-coated copper nanowires including chemically producing copper nanowires and coating the surface of the copper with silver using a silver-ammonia complex solution and a reducing agent in order to prevent oxidation of the copper nanowires by chemical reduction, and silver-coated copper nanowires having a core-shell structure produced by the method. In addition, production costs can be reduced because copper nanowires can be produced by reusing solutions.
