CONDUCTIVE INK, PREPARATION METHOD THEREOF AND CONDUCTIVE BOARD

摘要

PROBLEM TO BE SOLVED: To provide a conductive ink having a low firing temperature, high stability of dispersion and high conductivity.

SOLUTION: A first aspect of the present invention provides a conductive ink wherein a metal mixture of a metal precursor and an amine-based compound and metal nano particles capped by a dispersant are mixed in an organic solvent. A second aspect of the invention provides a preparation method of a conductive ink including the steps of: forming a metal mixture by mixing a metal precursor with an amine-based compound; and mixing the metal mixture with metal nano particles capped by a dispersant in an organic solvent. A conductive board of the present invention exhibits high conductivity even at low firing temperatures by using the above-described conductive ink.
