CONDUCTIVE INK COMPOSITION WHICH DOES NOT FORM A PARTICLE AND PREPARATION THEREOF

摘要

PURPOSE: A conductive ink composition is provided to avoid the coherence of particles since particles are not formed and the injection of separate nano particles due to high metal content. CONSTITUTION: A conductive ink composition comprises: a metal compound obtained by adding a mixture of C10-22 fatty acids and C2-9 fatty acids and ammonia into a metal precursor aqueous solution; an amine compound; and a solvent. A method for preparing the conductive ink composition comprises the steps of: (i) dissolving a metal precursor in water to prepare an aqueous solution; (ii) adding a mixture of C10-22 fatty acids and C2-9 fatty acids and ammonia into a metal precursor aqueous solution to obtain a metal compound; (iii) washing and drying the metal compound; and (iv) dissolving the dried metal compound and the amine compound in a solvent.
