Abstracts
Cu nano-colloid was prepared by wire electric explosion process under de-mineralized water and anhydrous ethanol.
To control the properties of Cu nano-colloid, experimental conditions such as diameter of Cu wire and applied voltage
were changed. The optimal Cu nano-colloid was prepared when the 0.1§® diameter of Cu wire with the applied
voltage of 2000 V was used. The shape of Cu particles in colloid was spherical and the XRD result revealed that
the phase of Cu particles was cubic phase. About 20§¬ Cu nanoparticles with high crystallinity were successfully
prepared using wire explosion process under anhydrous ethanol and they showed more than 100 hours dispersion
stability.
