Exploring electrodeposited iron and iron oxide nanostructures on porous alumina membrane for enhanced EMI shielding

[Display omitted] •Iron oxide nanowires were manufactured via electrodeposition.•An innovative approach to EMI shielding using nanowires electrodeposited within porous alumina membranes was investigated.•Metallic iron nanowires showed superior electromagnetic interference shielding than iron oxide nanowires. In this study, we are dedicated to researching innovative materials for controlling electromagnetic interference (EMI), with a special focus on iron and iron oxide nanostructures grown on porous alumina membranes. We thoroughly investigated the iron nanowires (FeNW) and oxide structures, exploring their behaviors under various oxidation conditions, including exposure to regular atmospheric conditions and oxygen flow at 600 °C. The results reveal that oxidation significantly degrades the EMI shielding performance of the FeNW composite materials. Although the average Electromagnetic Interference (EMI) shielding effectiveness for iron nanowire composites is slightly below the values found in the literature, the EMI shielding effectiveness per thickness demonstrates a promising upward trajectory. In conclusion, our study offers valuable insights into utilizing iron and iron oxide nanostructures to mitigate EMI-related challenges, driving advancements in EMI shielding technologies and strengthening the reliability of electronic devices and systems in our increasingly interconnected world.
