Organic Coating for Oxide Removal on Copper Surfaces

Abstract

The oxidation of copper surface decreases the surface functional quality, which can be detrimental for several industrial applications. The objective of my research project is the one-pot reduction of copper oxides on copper surfaces, followed by the formation of a stable coating composed of organic molecules that prevent further oxidation. The organic coating will be deposited using four approaches: immersion, resonant acoustic mixing, vapor phase deposition, and electrochemical deposition. By applying mentioned deposition methods, preliminary tests were performed and further characterized by using X-ray photoelectron spectroscopy (XPS) and matrix assisted laser desorption ionization (MALDI), which confirmed the presence of organic molecules on the copper surface. To obtain best coating, optimization is being done by varying various parameters such as concentration of organic molecule solution, time of immobilization, solvent type and influence of temperature. After achieving an optimal coating, next step forward is to conduct bulk corrosion studies to understand the real effect of the coating. Protecting copper surfaces in such a manner can extend the lifetime of copper surfaces, thereby saving resources, time and money in target industrial applications. Figure 1
