Eco-Friendly Protection of Copper via Self-Assembled Monolayer Films: The Critical Effect of Pollen Source Region on Anti-Corrosion Behavior

High Resolution Image Download MS PowerPoint Slide Background: This study initially investigates the corrosion inhibition efficiency of SAM films (self-assembled monolayer) derived from Bingöl pollen collected from various source regions on copper in a 3.5% NaCl environment. The films were designated as B-pollen(X)/SAM, where X represents the specific region. Methods: For a comprehensive understanding, the resulting SAM film characteristics on the copper substrate were analyzed using complementary techniques, including Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX), and contact angle measurements. Subsequently, a range of electrochemical techniques was employed to precisely quantify how regional variations in pollen source affect copper corrosion protection. The SAM film derived from Karlıova region pollen exhibited the highest corrosion inhibition efficiency on copper in 3.5% NaCl. Significant Findings: Overall, this study establishes that geographical source is a critical factor for optimizing the efficiency of pollen-derived SAM films, providing a sustainable and cost-effective pathway for the development of highly effective metallic protection systems.
