CONDUCTIVE NANO INK USING COPPER NANO GEL COMPOSITION AND PREPRATION METHOD OF THE SAME

摘要

Provided in the present invention is a conductive copper nano ink comprising a copper gel composition dispersed in an organic solvent. The copper nano ink of the present invention has an excellent dispersibility of nanoparticles, can be sintered by a thermal treatment under relatively low temperature of 100-300°C, and includes a fine polymer film surrounding copper nanoparticles not to be oxidized even after a thermal treatment in air, thus forming a copper pattern with an excellent conductivity.
