METHOD FOR PREPARING NANO COPPER OXIDE AND METHOD FOR PRINTING WITH METAL-BASED INK

摘要

Provided is a method for preparing a nano copper oxide. The method comprises the following steps: preparing a first dispersion by using a copper source; preparing a second dispersion by using a strong base; and mixing the first dispersion and the second dispersion, refluxing, stirring and reacting same at 100°C-180°C for 10 min-60 min, and separating the resulting reaction solution and retaining the solid, which is the nano copper oxide. Also provided is a method for printing with a metal-based ink, in which the above-mentioned prepared nano copper oxide is used.
