Abstract:
The present process provides a method for synthesizing oxide-free copper nanometal dispersion in a free and reduced state using a solution phase synthesis process. A solution of an organic reducing agent containing at least two proximal nitrogen atoms is reacted with a separate solution containing a copper salt reformulated into a charge transfer complex. The reaction products are stabilized with Lewis bases and Lewis acids and optionally can be concentrated by removing a portion of the volatile low molecular weight solvent by either the use of a partial vacuum or by chemical extraction into another phase.
