Abstract Underwater superoleophobic materials have shown promising applications in various fields, especially in the highly frequent oil‐spill accidents. However, the transparency and mechanical properties of existing underwater superoleophobic materials are generally mutually exclusive. In this work, a transparent and mechanically robust underwater superoleophobic film is presented by combining superspreading and biomineralization. Unlike the conventional hydrogel‐based materials, the transparent mineralized film exhibits significantly improved mechanical properties, which lead to a robust underwater superoleophobicity and an ultralow oil adhesion. Such a bioinspired mineralized film can be coated on various transparent supporting materials such as glass, polystyrene (PS), poly(ethylene terephthalate) (PET), and polypropylene (PP), showing promising applications in various fields, such as goggles, underwater cameras, and submarines.
