PREPARATION OF THE PD CATALYTIC INK, METHOD FOR FORMING METAL PATTERN USING THE SAME AND METHOD FOR THE SURFACE MODIFICATION OF SUBSTRATE

摘要

PURPOSE: A palladium catalyst ink composition is provided to be economic, to have very low viscosity and surface tension, and to have excellent storage stability, thereby capable of large-scale manufacturing printed circuits through roll to roll inkjet printing. CONSTITUTION: A palladium catalyst ink composition comprises palladium salt, ammonium salt, and a stabilizer. A manufacturing method of palladium catalyst ink comprises: a step of manufacturing ink by mixing palladium sat and ammonium salt in a solvent; and a step of adding stabilizer to the ink, and filtering the product. A metallic patterning method comprises: a step of inkjet printing the palladium catalyst ink composition on a substrate; a step of reducing the substrate; and a step of forming metallic pattern through electroless plating on the substrate.
