Title:
METHOD FOR MANUFACTURING SILVER-COATED COPPER NANOWIRE HAVING CORE-SHELL STRUCTURE BY USING CHEMICAL REDUCTION METHOD
Document Type and Number:
Japanese Patent JP2021021146
Kind Code:
A
Abstract:
To provide a method for manufacturing a silver-coated copper nanowire having high economic efficiency and productivity, as well as high resistance to oxidation.SOLUTION: There is provided a method for manufacturing a silver-coated copper nanowire, comprising a step of manufacturing a copper nanowire by a chemical method, and then coating the surface of copper with silver through a chemical reduction method by using a silver nitrate-ammonia complex solution and a reducing agent in order to prevent oxidation of the copper nanowires.EFFECT: Costs can be reduced since the copper nanowire can be reproduced by reusing a solution. Since the oxidation of the silver-coated copper nanowire having a core-shell structure according to the present invention is prevented even in air or at a high temperature, electrical conductivity does not deteriorate, and thus the silver-coated copper nanowire having a core-shell structure is useful in the manufacture of an electromagnetic shielding paste or a highly conductive paste, which requires a high electrical conductivity.SELECTED DRAWING: Figure 10
