CONDUCTIVE METAL NANO PARTICLE INK AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A conductive metal nanoparticle ink with enhanced dispersibility and a manufacturing method thereof are provided to enhance dispersibility, jettability and to lower resistivity. CONSTITUTION: A conductive metal nanoparticle ink comprises 10-90 weight% of metal nanoparticles obtained through electrolysis and 10-90 weight% of ink solvent. In the metal nanoparticle, dispersant is the capped. A manufacturing method of the conductive metal nanoparticle ink comprises the following steps: separating metal nanoparticles after removing electrolyte and dispersant from metal nanoparticle colloid solution(s12); and dispersing and pulverizing the metal nanoparticles by putting the metal nanoparticle into bead mill with ink solvent(s14).
