Drop cast coating of leather dye on copper and investigation of its corrosion behavior in sodium chloride solutions

Synthesis of mint leaf extract and mint-leaf-based NiO nanoparticles, coating of extract layers without and with NiO nanoparticles on copper through drop-casting, and their analysis for the corrosion prevention in saline water

“…Some standard methods of corrosion prevention have been practiced by researchers to protect Cu; however, it is reported that coating Cu with protective materials (barrier or cathodic protection) can be used in many cases for the successful protection of Cu. 6,7 Simple methods of coating, such as spin coating, 8 dip coating, 9 and drop casting, 10 can be exploited to generate protective films of materials over Cu; alternatively, complex techniques such as the atomic layer deposition, 11 Langmuir-Schaefer, 12 and chemical vapor deposition 13 techniques can also be used for film generation, depending on the requirements and quality of the film generation. Among the various methods available for coating, drop-casting has been selected in this work due to its cost-effectiveness, simple procedures, and film generation quality.…”
