Abstract

The interesting oil-wetting behavior to a superamphiphobic surface in water has been investigated. We demonstrated that the trapped air can tune the underwater wettability of the surface, changing from superoleophilic to superoleophobic. The trapped air in the grooves of the superamphiphobic surface can cause the significant change of the three-phase contact line (TCL).
