Preparation of copper nanofluids using an appropriate technique

Abstract

This work focuses on the synthesis of copper nanoparticles. The synthesis involves the use of copper nitrate, polyvinylpyrrolidone (pvp), dextrose and water as the copper precursor, stabilizing agent, reducing agent and solvent respectively.The nanoparticles were characterized by UV-visible spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering (DLS). An absorption peak at 580 nm in Uv-Vis spectrophotometer was detected indicating the presence of copper nanoparticles. The DLS analysis showed Copper nanoparticles with size of 5- 25 nm.
