ELECTROCONDUCTIVE SILVER NANO PARTICLE COMPOSITE, INK AND METHOD FOR PREPARING THE SAME

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.
