Superhydrophobic and superoleophilic cuttlebone with an inherent lamellar structure for continuous and effective oil spill cleanup

• Superhydrophobic and superoleophilic cuttlebone (SSCB) was successfully prepared. • SSCB retains the lamellar porous structure and offers fast anisotropic transport. • SSCB could separate both immiscible oil/water mixture and water-in-oil emulsions. • SSCB has excellent oil absorption capacity, recyclability, and high stability. • Fast continuous oil recovery was achieved by a novel “cephalopod” electric device. Oil wastes pose an enormous...
