    Abstract: A method of fabricating copper nanoparticles includes heating a copper salt solution that includes a copper salt, an N,N-dialkylethylenediamine, and a C6-C18 alkylamine in an organic solvent to a temperature between about 30° C. to about 50° C.; heating a reducing agent solution that includes a reducing agent, an N,N-dialkylethylenediamine, and a C6-C18 alkylamine in an organic solvent to a temperature between about 30° C. to about 50° C.; and adding the heated copper salt solution to the heated reducing agent solution, thereby producing copper nanoparticles. A composition includes copper nanoparticles, a C6-C18 alkylamine and an N,N'-dialkylethylenediamine ligand. Such copper nanoparticles in this composition have a fusion temperature between about 100° C. to about 200° C. A surfactant system for the stabilizing copper nanoparticles includes an N,N'-dialkylethylenediamine and a C6-C18 alkylamine.

    Abstract: Processes for synthesizing metal nanoparticles, particularly copper nanoparticles, are described. The processes can involve reacting an insoluble complex of a metal salt with a reducing agent in a reaction mixture containing a primary amine first surfactant, a secondary amine second surfactant, and a diamine chelating agent third surfactant. More specifically, processes for forming copper nanoparticles can involve forming a first solution containing a copper salt, a primary amine first surfactant, a secondary amine second surfactant, and a diamine chelating agent third surfactant; allowing an insoluble complex of the copper salt to form from the first solution; combining a second solution containing a reducing agent with the insoluble complex; and forming copper nanoparticles from the insoluble complex. Such copper nanoparticles can be about 10 nm or smaller in size, more particularly about 3 nm to about 6 nm in size, and have a fusion temperature of about 200°C or lower.

    Abstract: Metal nanoparticles and compositions derived therefrom can be used in a number of different applications. Methods for making metal nanoparticles can include providing a first metal salt in a solvent; converting the first metal salt into an insoluble compound that constitutes a plurality of nanoparticle seeds; and after forming the plurality of nanoparticle seeds, reacting a reducing agent with at least a portion of a second metal salt in the presence of at least one surfactant and the plurality of nanoparticle seeds to form a plurality of metal nanoparticles. Each metal nanoparticle can include a metal shell formed around a nucleus derived from a nanoparticle seed, and the metal shell can include a metal from the second metal salt. The methods can be readily scaled to produce bulk quantities of metal nanoparticles.
