Preparation, characterization and thermo-physical properties of Cu-graphene nanoplatelets hybrid nanofluids

Abstract

In this study, Copper-graphene hybrid nanoparticles are prepared by physical method and the nanofluid is prepared with distilled water along with CTAB (Copper coated trimethylammonium bromide) as surfactant. The thermophysical properties of hybrid nanofluid also found for different hybrid nanoparticle concentrations. The surface characterization of the hybrid nanoparticles is performed by SEM (scanning electron microscope), EDX (Energy Dispersive X-Ray Analysis) techniques. The hybrid nanofluids are found to be stable even after a month without any deposition using a stabiliser. Thermal conductivity, viscosity and density of 0.02% hybrid nanofluids are enhanced by 9.95%, 13.5% and 12.5% in comparison to the distilled water.
