Characters of Particles in Copper-Water Nanofluids Made by Novel One-Step Aqueous Reduction

Abstract:

Copper-water nanofluids were obtained by a novel one-step KBH₄ aqueous reduction of copper sulfate with complex compound EDTA-2Na and quaternary ammonium cationic dispersant C₁₆H₃₃(CH₃)₃NBr (CTAB). The average particle size of the nanofluids with 4g CTAB in 200ml solution was only 1.02nm measured by dynamic light scatter particle size analyser. The obtained powders centrifuged were pure copper mostly and contained a litter Cu₂O which were influenced by the chemical reaction of complex compounds EDTA-2Na.
