Comparison of exterior texture and wettability of Pinctada margaritifera & CaCO3-SF thin film. a–d Top-view SEM images of the exterior micro-/nano-textures surfaces of Pinctada margaritifera a, b & a prismatic CaCO3-SF thin film (i.e., [SF] = 4 g L−1) c, d. e–h Photographs showing the superoleophobicity and low adhesion of the corresponding Pinctada margaritifera e, f and a prismatic CaCO3-SF thin film g, h. Abbreviations W and O represent water and 1,2-dichloroethane, respectively. Each oil droplet is 3 μL in volume
