With the rapid development of the marine transportation and oil exploration industries, oil spill accidents, such as ship

discharges and leakages from oil transport vessels and off shore drilling platforms, occur from time to time, turning oil spill

pollution at sea into an increasingly serious problem. Therefore, developing a rapid and effi cient oil spill pollution treatment

is of great signifi cance to protect the water environment. In this study, we used a simple dip-coating method to modify polydimethylsiloxane

and nano-alumina onto a polyurethane sponge skeleton to prepare a super-oleophilic/super-hydrophobic

porous adsorbent called Al 2 O 3 @PDMS/PU. The prepared Al 2 O 3 @PDMS/PU has a contact angle of 156.8° with water and

can adsorb oil or organic solvents equivalent to 16–38 times its own weight. Based on the excellent super-oleophilic/superhydrophobic

properties of Al 2 O 3 @PDMS/PU, we designed an oil collection device that can continuously recover oil and

organic solvents. Unlike the traditional oil recovery method, this device integrates the oil–water separation and oil recovery

processes such that the adsorption capacity of the adsorbent is no longer limited by its own weight and volume. This device

shows broad application prospects in emergencies, such as oil leakages from drilling platforms and organic solvent leakage.
