Nanofluid has gained vast attention as a novel heat transfer working fluid owing to its superiority in thermal conductivity and rheol. properties. Meanwhile, the liquid range and the stability of nanofluids are of great significance since it dominates the utilization scope of a working fluid. In this work, with the aim at solving the poor stability associated with short liquid range of traditional nanofluids, a novel “one-step” preparation protocol was developed using Cu(OH)2 as a precursor and deep eutectic solvents (DESs) as dispersing medium. The as-prepared nanofluid bears an extraordinary static stability that can be kept for at least two months without observation of any sedimentation thanks to the in-situ formed Cu2O nanoparticle in DESs under a microwave irradiation condition and wide liquid range attributed to the low saturated pressure of DESs. Structural anal., such as SEM, TEM, XRD, XPS and FTIR anal., and thermophys. properties of the nanofluids were subject to a comprehensive study. Thermal conductivity anal. indicated that the presence of Cu2O nanoparticle slightly impacts the thermal conductivity when the mass fraction of the nanoparticle is small. Notably, this DESs based nanofluid features promising photothermal conversion that can reach 83.74% with the addition of 0.1 wt% Cu2O nanoparticle. This study provides an important avenue for the preparation of nanofluids with high static stability. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Safety of Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to low toxicity and inexpensive, earth-abundant. These ligands enable the reaction promoted in mild condition. The reaction scope has also been greatly expanded, rendering this copper-based cross-coupling attractive for both academia and industry.
