“…Corrosion causes major damage in many major industries (automotive, construction, aerospace, oil and gas, etc.). [1][2][3][4][5][6][7][8][9] For example, various inhibitors are used to reduce copper corrosion 10 including molecules and compounds such as benzotriazole, 11,12 imidazole derivatives, [13][14][15] Schiff bases, 16,17 green corrosion inhibitors, [18][19][20] ionic liquids, 21,22 smart coatings, 23 drugs, [24][25][26] nanomaterials, [27][28][29] etc. To our knowledge, there are limited studies on the use of carbon nanotubes containing aryl radicals of the same diazonium salt 30 and there are no studies on the fermentation of carbon nanotubes with aryl resins from diazonium salts, even though such layers have been shown to reduce the corrosion of metals [31][32][33][34][35] and are easy to apply as a surface treatment.…”

In order to develop novel unexplored potential corrosion inhibitors, covalently modified single-walled carbon nanotubes (SWCNT) via benzoic (–PhCOOH) and aniline (–PhNH2) groups are being investigated as corrosion inhibitors for the first time. Utilizing a comprehensive approach, this study employed density functional theory (DFT), Monte Carlo (MC), and molecular dynamics simulations (MD) to assess the adsorption behavior of modified nanotubes as corrosion inhibitors on the Cu(111) surface within a simulated aqueous HCl corrosion medium. The results provided molecular information on the adsorption capability, geometry adsorption centers, and adsorption energies (Eads) of carbon nanotubes on the surface of Cu(111). The adsorption energy values unveiled robust interactions between SWCNT–PhCOOH and SWCNT–PhNH2 inhibitors and the Cu(111) surface, suggesting a highly effective corrosion protection mechanism. The calculated Eads values exhibited notable ranges, spanning from –260.82 to –308.18 kcal/mol for SWCNT–PhCOOH and –220.92 to –261.01 kcal/mol for SWCNT–PhNH2 with the maximum probability values, representing the most favorable adsorption scenarios, determined to be –292.96 and –229.39 kcal/mol, respectively. A key insight from Monte Carlo simulations underscored the inherent spontaneity of the adsorption process, corroborated by the consistently negative Eads values. These findings collectively underscore the substantial affinity of the inhibitors to the copper surface, contributing to a deeper comprehension of their corrosion inhibition capabilities.

“…The widely used copper-plating process uses cyanide ions, which can cause serious environmental pollution problems [ 27 , 28 ]. Other methods, such as plasma treatment with oxygen, chemical vapor deposition, and ammonia plasma, require complex equipment and procedures [ 29 , 30 , 31 , 32 ]. Therefore, to widely apply the antibacterial properties of copper, a new method to solve these problems is important.…”

Copper Surface Treatment Method with Antibacterial Performance Using “Super-Spread Wetting” Properties

et al. 2022

In this work, a copper coating is developed on a carbon steel substrate by exploiting the superwetting properties of liquid copper. We characterize the surface morphology, chemical composition, roughness, wettability, ability to release a copper ion from surfaces, and antibacterial efficacy (against Escherichia coli and Staphylococcus aureus). The coating shows a dense microstructure and good adhesion, with thicknesses of approximately 20–40 µm. X-ray diffraction (XRD) analysis reveals that the coated surface structure is composed of Cu, Cu2O, and CuO. The surface roughness and contact angle measurements suggest that the copper coating is rougher and more hydrophobic than the substrate. Inductively coupled plasma atomic emission spectroscopy (ICP-AES) measurements reveal a dissolution of copper ions in chloride-containing environments. The antibacterial test shows that the copper coating achieves a 99.99% reduction of E. coli and S. aureus. This study suggests that the characteristics of the copper-coated surface, including the chemical composition, high surface roughness, good wettability, and ability for copper ion release, may result in surfaces with antibacterial properties.
