New Research Enhances Copper Coatings for Cost-Effective Construction Solutions

Recent research conducted by a team of scientists from Shenyang Ligong University and other institutions has unveiled promising advancements in the electrodeposition of copper, a process crucial for various applications in the construction sector, including electrical wiring and plumbing. The study, led by Liu Yang and colleagues, explored the effects of several additives on the electrodeposition of copper using a low eutectic solvent—choline chloride and glacial acetic acid (Ch Cl-Gl A).

The research highlights the potential of these additives, particularly ascorbic acid, to enhance the quality and performance of copper coatings. “Our findings indicate that ascorbic acid significantly improves the deposition process, allowing for the creation of high-performance copper coatings at room temperature,” said Liu Yang. This is particularly relevant for industries seeking efficient and cost-effective methods for copper deposition, as the ability to operate at room temperature can reduce energy consumption and operational costs.

Using electrochemical techniques such as cyclic voltammetry and chronoamperometry, the team investigated the underlying mechanisms of copper deposition. They discovered that the process involves a two-step oxidation-reduction reaction, which ultimately contributes to the formation of a more uniform and high-quality copper layer. The study also employed scanning electron microscopy and X-ray diffraction to analyze the morphology and composition of the deposited coatings, revealing distinct improvements in grain structure when additives were employed.

The implications of this research extend beyond the laboratory. In the construction sector, where the demand for reliable and durable materials is ever-increasing, the ability to enhance copper deposition processes can lead to better-performing electrical components and longer-lasting plumbing systems. The findings suggest that the integration of these additives could revolutionize the manufacturing processes, potentially lowering costs and improving the durability of copper-based products.

As the team noted, the average grain sizes of the copper layers produced with additives were notably smaller compared to those without, which is a significant factor in the performance of the coatings. This could lead to enhanced conductivity and corrosion resistance, key attributes for materials used in construction.

This groundbreaking work was published in ‘Cailiao Baohu’, which translates to ‘Materials Protection’. As industries continue to seek innovative solutions to meet growing demands, the advancements in electrodeposition techniques highlighted by Liu Yang and his team could pave the way for new standards in material performance and sustainability in construction.
