Title:

METHOD FOR PREPARING COPPER NANOPARTICLES AND NANO-INK USING UNDERWATER DISCHARGE

Document Type and Number:

WIPO Patent Application WO/2015/199459

Kind Code:

A1

Abstract:

The present invention provides a method for preparing nanoparticles and an ink containing the nanoparticles, wherein the method comprises the steps of: preparing an aqueous copper precursor solution (S1); synthesizing nanoparticles using underwater discharge in the prepared aqueous solution (S2); collecting copper nanoparticles generated by the underwater discharge (S3); and dispersing the collected nanoparticles in an ink composition for digital printing containing a hydrophilic organic solvent and an aqueous dispersant, thereby synthesizing a nano-ink.
