CONDUCTIVE SILVER NANOPARTICLE COMPOSITE CAPABLE OF MANUFACTURING AN INK HAVING A LOW SINTERING TEMPERATURE AND EXCELLENT SPECIFIC RESISTIVITY, THE INK, AND A METHOD FOR MANUFACTURING THE COMPOSITE

摘要

PURPOSE: A conductive silver nanoparticle composite is provided to prevent the oxidation of copper by mixing the silver nanoparticles with a copper flake which is coated with the silver and to improve specific resistivity properties.;CONSTITUTION: A conductive silver nanoparticle composite includes a copper flake which is coated with silver and has a plate shape and silver nanoparticles. The length of a longitudinal axis of the copper flake is 2~12 microns and the thickness is less than 100nm. A method for manufacturing a conductive silver nanoparticle ink comprises: a step(S100) of preparing a dispersed liquid; a step(S110) of putting the copper flake and silver nanoparticles into the dispersed liquid; and a step(S120) of forming the ink of paste phase through a stirring process.;COPYRIGHT KIPO 2010
