Title:
化学的還元法を用いたコアシェル構造の銀コーティング銅ナノワイヤの製造方法
Document Type and Number:
Japanese Patent JP7361158
Kind Code:
B2
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. The method of preparing silver-coated copper nanowires having a core-shell structure according to the present invention can avoid deterioration in electrical conductivity by preventing oxidation even in the air or at high temperatures, thus being useful for the production of electromagnetic shielding paste or highly conductive paste requiring high electrical conductivity.
