Magneto-responsive nano-oil coating for anticorrosion, anti-biofouling, and drag reduction
Abstract The development of ideal marine-engineering materials is confronted with problems associated with corrosion and sailing resistance. In the current study, we prepared a Fe3O4 nanoparticle-based nano-oil and employed it to form a slippery liquid-infused porous surface (SLIPS) on 2024 aluminum alloy. As synthesized, the SLIPS reduced drag in a sailing experiment by 30% and biofouling by 99.7%, and exhibited a more than 2 orders of magnitude greater anticorrosion performance. Owing to its integrated functions for drag reduction, anti-biofouling, and anticorrosion, the newly uncovered Fe3O4 nanoparticle-based nano-oil has great potential for applications in marine material engineering.
