Synthesis of Water Loaded CuAlO2 Nanoplatelet Based New Generation Nanofluid Using Hydrothermal Approach: A Detailed Insight of Structural, Electrical, and Viscous Properties
In this study, water loaded delafossite CuAlO2 nanoplatelet based new generation nanofluid was successfully synthesized for the first time. The delafossite CuAlO2 nanoplatelets were prepared using the hydrothermal method at low temperature. The morphological and structural properties of the CuAlO2 Nanoplatelets were analyzed using X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high-resolution TEM (HR-TEM), and selective area electron diffraction (SAED). The XRD data confirmed the formation of single phase rhombohedral CuAlO2 with an average crystallite size of 11 nm. The FESEM and TEM images revealed that the synthesized particles were almost platelets with an average size of 12 nm. The absorbance spectra and zeta potential were examined to study the stability of the fabricated nanofluids. The electrical conductivity, dielectric constant, and viscosity of CuAlO2 nanoplatelets were measured on the basis of weight fraction and temperature.
