Copper has extensive industrial applications. However, the susceptibility to corrosion makes it vulnerable in harsh environments. Bioinspired coating presents a novel approach to address copper corrosion. Bioinspired from lotus leaves and pitcher plants, this research endeavors to create superhydrophobic and ferrofluid-infused surfaces (FIS) on copper substrate. Firstly, a one-step electrodeposition method is employed to fabricate superhydrophobic surface on copper. Secondly, Fe3O4 nanoparticles are sequentially modified with dopamine hydrochloride and dodecanethiol to endow surface hydrophobicity. Then, the modified Fe3O4 is dispersed in oil to create a magnetic fluid, which is finally infused onto the superhydrophobic matrix, forming the FIS coating. Electrochemical testing confirms the high protective effect of the bio-inspired superhydrophobic and magnetic fluid composite coating against corrosion. The FIS coating exhibits a prominent low-frequency impedance modulus (7.73 × 106 Ω·cm²) even after immersion in NaCl solution for 60 d. Furthermore, the coating demonstrates an outstanding magnetic-driven self-healing capability, as evidenced by the minimal decrease in the |Z|0.01 Hz value (remaining as high as 109 Ω·cm²) even after undergoing six cycles of scratching and self-healing process. This corrosion resistance can be attributed to the combined effects of the accommodating effect of superhydrophobic matrix and the self-healing property of the magnetic fluid under the magnetic field. This dually bio-inspired coating technology offers significant advantages for copper applications in harsh environments.
