The Synthesis and Characterization of Metal Nanoparticles Using a Modified Electrolysis Method for Conductive Ink in Ink-Jet Printing Technology
In the ink-jet patterning process, conductive ink composed of metal nanoparticles and solutions, is an important factor for improving properties of printed patterns and processes. In this study, metal (Cu) nanoparticles in conductive ink were synthesized using a modified electrolysis method that extracted to metal nanoparticles from bulk metal plates. The Cu nanoparticles were prepared with a narrow size distribution. The dispersion stability and oxidation properties in conductive inks were also studied. Cu nanoparticles were homogeneous and had a diameter of 15∼20 nm. By addition of PVP, the dispersion and oxidation stability of the metal nanoparticles, which were not oxidized after 2 month, were improved.
