EXAMPLE - The heat transfer composition was formed by using copper powder having copper particles of average particle size of 50 nanometers (nm). The powder was chemically modified with tolyltriazole by dissolving 3 wt.% copper powders in tolyltriazole solution with methyl ethyl ketone and stirred on magnetic stirring hot plate. The copper powder was reduced to powder of 50 nm average particle size. The resulting copper powder was slurried in the solution for 15 minutes at 50-55degreesC. The coated product was isolated by filtration, washed with solvent, and allowed to dry. The resulting product demonstrated enhanced thermal transfer properties and dispersion characteristics when combined with heat transfer media.
