Abstract
Copper oxide (CuO) nanofluids are prepared by two step method. CuO nanoparticles are prepared by sol gel method with Copper chloride as precursor and NaOH as a reducing agent. The prepared CuO nanoparticles are characterized by XRD, SEM and Particle size analyzer. XRD measurements reveal a grain size of 72nm .SEM image reveals an inhomogenous mixture of particles from 500 nm to 3500 nm with irregular morphology and few traces of CuO cones.. The particle size distribution of CuO particles is in the range of 1000-1600nm which is in accordance with the SEM results.CuO –Ethylene Glycol nanofluids are prepared by two step method by ultrasonication of obtained CuO particles.The stability of CuO nanofluid is given with a negative zeta potential of-22.5 mv.
