CONDUCTIVE INK, METHOD FOR PRODUCING THEREOF AND CONDOCTIVE SUBSTRATE

摘要

Provided are a conductive ink having a low firing temperature, high dispersion stability and excellent electroconductivity, and a conductive substrate having excellent conductivity at a low firing temperature by using the same ink. The conductive ink comprises a mixture of: a metal mixture comprising a metal precursor with an amine compound; metal nanoparticles capped with a dispersant; and an organic solvent. The metal precursor and the metal nanoparticles comprise at least one metal element selected from the group consisting of silver(Ag), copper(Cu), nickel(NI), gold(Au), platinum(Pt), palladium(Pd) and iron(Fe). The metal precursor is at least one selected from the group consisting of AgNO3, AgBF4, AgPF6, Ag2O, CH3COOAg, AgCF3SO3, AgClO4, Cu(NO3), CuCl2, CuSO4, NiCl2, Ni(NO3)2 and NiSO4.
