Abstract Although floating oil with large particle sizes can easily be separated from water by membrane separation
methods, tiny oil droplets with tremendously small volume force and density gradient at oil-water interfaces
within water lead to barriers of oil-water separation. Consequently, tiny oil droplets remain in the water,
resulting in energy waste, environmental pollution and biological health hazard. Traditional super-wetting
membranes with extremely small pore sizes were easily blocked during the oil-water separation process.
Inspired by the cactus and rice leaf, we developed a superhydrophobic-superoleophilic surface with conical
micro-arrays to realize ultrafast adsorption of tiny oil droplets within the water. The… More >
