Unleashing the antibiofouling potential of nano-structured ZrN-Cu coating through electricity
The world needs more environmentally friendly materials every time, especially when the application demands constant interaction with fragile habitats. The naval industry is a crucial player in a globalised economy, and the ambient impact of ships on the seas is well-known. Biofouling is one of the significant issues in this industry, and paints with biocides are used as the principal coating solution. However, those are mechanically poor, releasing heavy pollutants into the oceans. Multifunctional coatings obtained by PVD technology could help overcome this situation. The present study proposes a solution to create an advanced coating composed of zirconium nitride and copper in a specific nano-architecture. The developed coating was obtained in a hybrid magnetron co-sputtering system, employing high-power impulse and direct current power sources in a reactive atmosphere. SEM and TEM expose the morphology and the structure of the coatings. EDX, RBS, and XPS were used to assess the chemical insights of the coating. Halo and biofilm tests (with Cobetia marina) were employed to evaluate the antibiofouling action of the coating. The results showed that the activation of the coating, regardless of the used method, provoked the copper migration to the surface, being crucial to obtaining the antibacterial action (reduced bacteria adhesion and > 3 log reduction in CFU on the surface) without affecting the coating integrity (assessed by SEM), and not releasing heavy metals in a significant manner (< 2 log reduction CFU on supernatant). This opens the option of this kind of material, which is environmentally friendly, to be applied in real applications.
期刊介绍:
Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance:
A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting.
B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
