Highly stable copper/carbon dot nanofluid

摘要: Copper/carbon dot nanohybrids (Cu/CD NHs) were prepared via a facile precipitation method through disproportionation reaction. The surface characterization was performed by various techniques such as XRD, FTIR and TEM. Then, water-based nanofluids composed of Cu/CD NHs at 0.1 0.5 mass% prepared, their thermo-physical properties including thermal conductivity, viscosity, density specific heat evaluated temperatures. nanofluid demonstrated to be potential transfer fluid with high stability. It found that the conductivity can enhanced increasing nanoparticle concentration temperature. Almost 1.25-fold increase in has been achieved raising temperature up 50 °C 0.5 mass%. capacity concentration. Moreover, viscosity as-prepared decreased, whereas showed an trend.
