Abstract
The current effort is devoted to investigate the shiny thin film with a metallic tactile covering of nanoparticles over the surface of a rotating disk. To decorate, glowing silver and gold particles were chosen. Four illustrative base liquids, namely (i) ethanol, (ii) methanol, (iii) ethylene-glycol, and (iv) water were considered with different geometries, which have great importance in industrial usage. An emphasis on comparative multi nanofluid analysis was used to make a sound judgment on which one of the fluids best suited the metallic glittering process of spin coating. The film thickness process highly depends on the process of evaporation, which takes some time to settle on the disk’s surface. It was found that of the base fluids, the best choices were ethanol alloys with silver. Hence, one can conclude that from an experimental point of view, if silver alloy is used for coating, then only those liquids can be considered that exhibit ethanol-like properties. The impact of pertinent parameters with different aspects are graphically illustrated in each case.
Highlights
The mechanical process of covering the surface of an object/substrate with the help of a very thin layer is known as “Coating”
To serve the purpose of this study, four different kinds of Newtonian fluids having diverse physical and chemical properties are considered instead of non-Newtonian fluids because coatings with such types of fluids would have a tremendous impact on the cost, volume, weight, and mechanical properties of electronic, optoelectronic, and photovoltaic devices; this portion is dedicated to the parametric study of the proposed model in which four kinds of Newtonian fluids, such as water, ethanol, methanol and ethylene-glycol are opted for as the base fluids
The main reason to carry out this graphical work is to confirm whether or not the obtained mathematical results are in complete coherence with the physical expectation of the spin coatings
Summary
The mechanical process of covering the surface of an object/substrate with the help of a very thin layer is known as “Coating”. Apart from a process of simple coating, developing a uniform and thin film or covering to a spinning sample or substrate, is called “spin coating”. In the latter sort of coating, a small amount of liquid solution is placed at the center of the highly rotating disk, with the help of a pipette or syringe, resulting in the solution spreading uniformly and evenly in all directions as elaborated in [3].
