Abstract:
This objective of this research is to study the dispersion of copper oxide
nanoparticles in water as a nanofluid system. Copper oxide nanoparticles were
prepared by micro-emulsion method. Particle size and Morphology of copper
oxide was analyzed by TEM. The results showed that 42.1% of copper oxide has
an average particle size of copper oxide in the ranges of 10 to 19 nm as well as
copper oxide particle has a spherical shape and is well dispersed in water. The
stability of nanofluid was examine by dispersion of 0.15 %wt of copper oxide in DI
water. The pH of water was varied until the good dispersion of copper oxide was
achieved with 30 min of sonication time. The results showed that the best
stability of nanofluid system was obtained at pH 11.
