Method for manufacturing silver nanoparticle-containing ink, and silver nanoparticle-containing ink
Abstract:
Silver nanoparticle-containing ink which develops excellent conductivity by low-temperature calcining and has silver nano-particles stably and well dispersed in a dispersion solvent. Method for producing the silver nanoparticle-containing ink, by: mixing a silver compound with amines comprising an aliphatic hydrocarbon monoamine (A) comprising one amino group and an aliphatic hydrocarbon group having 6 or more carbon atoms in total; and further comprising at least one of: an aliphatic hydrocarbon monoamine (B) comprising one amino group and an aliphatic hydrocarbon group having 5 or less carbon atoms in total; and an aliphatic hydrocarbon diamine (C) comprising two amino groups and an aliphatic hydrocarbon group having 8 or less carbon atoms in total; to form a complex compound comprising the silver compound and the amines; thermally decomposing the complex compound by heating to form silver nano-particles; and dispersing the silver nano-particles in a dispersion solvent containing an alicyclic hydrocarbon.
