Manufacturing method of copper nanowires

Abstract

This invention provides a method for manufacturing copper nanowires, which yields copper nanowires with excellent selectivity and can be implemented with a simple structure. The method for manufacturing copper nanowires of this invention includes the following step 1: Step 1: Setting a mixture containing copper oxide (a), halide ions (b), a nonionic polymer compound (c), alkyl quaternary ammonium ions (d), a reducing agent (e), and water (f) to 50°C or higher to precipitate copper nanowires.
