Title:
METHOD FOR PRODUCING COPPER NANOINK
Document Type and Number:
Japanese Patent JP2018127712
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a copper nanoink, capable of easily producing a minute copper nanoink with high-concentration.SOLUTION: A method for producing a copper nanoink uses a copper nanoparticle dispersion with an average particle diameter of 50 nm or less, obtained by a liquid phase reduction method. The method for producing the copper nanoink includes: a film concentration step of separating a liquid phase by an ultrafilter membrane from the copper nanoparticle dispersion; and a centrifugal concentration step of centrifugal separation of the liquid phase from the copper nanoparticle dispersion.SELECTED DRAWING: Figure 1
