A method of producing low melting organoamine stabilized silver nanoparticles and use of same to form conductive features on a substrate

摘要

A process for producing organoamine stabilized silver nanoparticles, comprising: forming a heated solution comprising an organic solvent and a first amount of organoamine wherein the organic solvent is selected from the group consisting of toluene, heptane, hexane, benzene, cyclohexane, pentane, bromobenzene, chlorobenzene and mixtures thereof are selected, - adding a silver salt to the solution, - adding a second amount of organoamine to the solution, - adding a hydrazine derivative to the solution; and precipitating the silver particles from the solution by adding isopropanol to the solution; and recovering the organoamine stabilized silver nanoparticles; wherein the molar ratio of silver salt to the total added organoamine is from 1: 4 to 1:10.
