Synthesis of Novel CuO–Gelatin Nanofluids Using Ultrasonic Technique

Abstract

AbstractNanofluid molecular properties, such as acoustical properties, vary widely in system parameters and are influenced by liquid cohesive characteristics. Gelatin is a natural polymer made from the partial hydrolysis of collagen, which allows the triple helix to unfold and split, resulting in a polydisperse mixture of proteins in solution. The use of ultrasonic technology to create nanoparticles from biopolymer base fluids is a novel method of nanofluid synthesis. The focus of this research is to measure the ultrasonic velocity and density of synthesized nanoparticles using gelatin as the base fluid at various weight percentages. The study have synthesized the Copper oxide (CuO) nanofluid by transforming an unstable Cu(OH)2 to CuO as a precursor in aqueous gelatin by ultrasonication process. To characterize the prepared nanoparticles, the XRD and FESEM methods are used. The results of ultrasonic velocity, density, and viscosity measurements are discussed after ultrasonication. Experimental data and a theoretical approach to nanofluids are used to study the stability of nanofluids. The outcomes of ultrasonic spectroscopy and other investigations are very similar.
