The co‐effect of microstructures and mucus on the adhesion of abalone from a mechanical perspective

Abstract Reliable and reversible adhesion underwater is challenging due to the water molecules and weak layers of contaminants at the contact interface, which requires to deepen the understanding of wet adhesion of biological surfaces. Herein, the co‐effect of microstructures and mucus of abalone fo...
