Clam's shell inspired high-energy inorganic coatings with underwater low adhesive superoleophobicity.
Unique underwater low adhesive superoleophobicity is discovered on the pallium-covered region of a short clam's shell. This property originates from the shell's inorganic composition of CaCO(3)  and surface micro/nano-hierarchical structures. The oil-repellent shell provides an innovative strategy to develop novel underwater superoleophobic coatings using inorganic oxides such as copper oxide. This kind of coating is anticipated to be applied on engineering metals to protect aquatic equipment from oil contamination.
