Synthesis and Optimization of Metallic Nanofluids using Electrical Explosion of Wires in Liquids

摘要

Nanofluids, dispersed nano-sized particles in liquds have been drawing the attention for the research and industrial field. This study has been focusing on controlling the size, oxidation, and agglomeration of the nanoparticle by adjusting the plasma of EEWL and the base fluid, including water and ethanole and other common liquids. To identify the effect of the key parameters in EEWL, such as the applied electrical voltage, the capacitance, the type of metal wire and the solvent volume, the sensitivity analysis has been performed in terms of the size of nanoparticles. Based on this analysis, the optimization of the EEWL process for producing the metallic nanofluids has been carried out. In addition, the morphology of these metallic nanofluids was observed using high-resolution transmission electron microscopy.
