Seaweed (Saccharina japonica) is found to have excellent superoleophobicity in salt solutions, which results from its high content of polysaccharides. Inspired by this, coatings with salt-tolerant underwater superoleophobicity and ultralow oil adhesion are successfully fabricated using calcium alginate. During immersion in artificial seawater for 30 days, the coatings effectively repel various types of oil, including crude oil and viscous silicon oil, demonstrating their great potential as a marine oil-repellent coating.
