Document Type and Number:
WIPO Patent Application WO/2020/242049
Kind Code:
A1
Abstract:
The present invention pertains to a method for manufacturing an antibacterial copper nanopowder, and an antibacterial copper nanopowder manufactured thereby. More specifically, the present invention pertains to: a method for manufacturing an antibacterial copper nanopowder which is produced by electric wire explosion of a copper wire and has a film layer formed on the surface thereof; and an antibacterial copper nanopowder manufactured by the manufacturing method. The present invention provides: a method for manufacturing an antibacterial copper nanopowder which is produced by electric wire explosion of a copper wire and has a film layer formed on the surface thereof; and an antibacterial copper nanopowder manufactured by the manufacturing method, thus having the effect in which a copper nanopowder having enhanced antibacterial performance, less powder agglomeration, and a lower content of impurities can be mass-produced by a simple and highly energy-efficient process at a lower cost compared to conventional copper nanopowder manufacturing processes. In addition, the present invention has the effect in which a copper nanopowder is highly stable due to having a film layer, which is amorphous or comprises a mixture of amorphous and crystalline phases, formed thereon, and can be highly dispersed without being eluted, even when mixed into yarns or resins and the like.
