Robust underwater superoleophobicity – oil repellence that is stable under loading – is achieved by constructing hierarchical macromolecule‐nanoclay hydrogels (see images), inspired by the oil‐repellent nature of the composite surface of fish. The synergetic effect of micro‐/nanostructures and the mechanical strength of hybrid hydrogels in general supports the stability of trapped water on the hydrogel surface, endowing hybid hydrogels with robust superoleophobicity (upper right inset) even under loading forces.
