| Abstract: | A simple method for preparation of nanocrystalline copper powders through copper sulfate reduction by potassium borohydride in aqueous solution is described. The reduction process was studied in detail, and the parameters that influence the properties of the copper powders, such as effect of added complexing agent EDTA, the protective polymer PVP and surface modification agent SMA, were also investigated. Well-dispersed nanocrystalline copper powders were obtained, with average diameters of 28.4 nm and 40 nm depending on the conditions employed. |
