N-Heterocyclic carbenes deposition on copper powder surface using mechanochemistry

Industrial-scale corrosion leads to economic burdens, compromised safety, environmental degradation, and decreased operational efficiency, emphasizing the urgent need for effective corrosion prevention and mitigation strategies. Copper powder, as a low-cost industrial material, has a broad range of applications, such as semiconductor, electrically conductive paste, and spray coating, because of the excellent electrical conductivity and higher melting point. However, oxide layer cannot protect copper from further oxidation, leading to the gradual corrosion of the metal. Moreover, the presence of a surface oxide layer negatively affects the performance of copper powder in thermal spray technology, as its presence compromises the internal adhesion of industrial coatings. N-heterocyclic carbenes have been used as ligands for metal complexes and nanoparticles for decades, taking advantage of the strong covalent bond to metals and tunable side groups. Recently, the self-assembled monolayers (SAMs) of NHCs have attracted increasing attention as an alternative to thiol analogs on gold due to their chemical and thermal stability. The ability of NHC to form monolayer have also been demonstrated on other metal surfaces, like copper, silver, platinum, and magnesium. Among them, NHCs deposition on copper surface was extensively studied for its application on corrosion. In particular, a stable NHC precursor was reported to remove copper oxide and modify the metallic surface under ambient conditions. This opens a new avenue to modify copper for industrial applications. The main issue that this project tackles is the need to find chemical agents that remove the copper oxide from Cu spray powders and stabilizes them during industrial spray application.
