摘要:
The present invention relates to a method of producing copper nanoparticles, in particular to, a method of producing copper nanoparticles, including: preparing a first solution including a polar solvent, a dispersing agent and one or more reducing agents selected from the group consisting of sodium hypophosphates(NaH2PO2), hydrazine(N2H4), hydrochloride and sodium borohydride(NaBH4) and heating the solution; preparing a second solution including a polar solvent and a copper precursor and heating the solution; and injecting the heated second solution into the heated first solution at a time and mixing each other. According to the present invention, copper nanoparticles which are fine and uniform can be produced simply, and thus the method is useful in mass production of copper nanoparticles.

摘要:
Disclosed herein is a method for forming a metal wiring and an electrode using a metal nano paste, including a sintering process, wherein the sintering includes: placing a substrate on which a metal nano paste is printed in a furnace and raising a temperature of the furnace to 220 to 240° C. under a nitrogen atmosphere; heating the substrate under a mixed atmosphere of carboxylic acid and air while the temperature of the furnace is maintained at the temperature range;dropping the temperature of the furnace to 100 to 150° C. under the mixed atmosphere of carboxylic acid and air; and dropping the temperature of the furnace to room temperature under a nitrogen atmosphere. According to the present invention, a metal film having high density and a minimized amount of residual metal particles can be formed despite a low-temperature sintering process, like a case where a high-temperature sintering process is employed.
