Figure 2

Underwater oil wettability of the mineral-coated membranes.

(a) The contact angle and sliding angle of 1,2-dichloroethane (DCE) droplets on the membranes prepared from different mineral-coating cycles. Inset photographs show that the oil-adhesion declines after mineral-coating. (b) The wetting behavior of DCE droplets on the membranes that are immersed in DCE for a certain time. The membranes exhibit stable superoleophobicity. (c) The underwater superoleophobic property of the mineral-coated membranes for a series of oils.
