Abstract

Substrate-independent underwater superoleophobic surfaces are designed by combining two bio-inspirations: the remarkable oil-repellence of fish skin and the versatile anchoring ability of mussel-adhesive proteins. A mussel-inspired polymer is synthesized, showing strong underwater adhesion to various substrates. A fish-skin inspired top layer is then assembled on this polymer coating through a layer-by-layer process.
