As the ecological damage caused by marine oil spills has become one main threat to marine ecological security, materials that can reduce environmental pollution are in high demand. In this study, a simple low-cost method for fabricating a hydrophobic polyurethane sponge was investigated. Its hydrophobicity was evaluated through the measurement of the contact angles of water and oil. The mechanical properties, oil-absorption capacity, and selectivity were also tested. The results show that this sponge exhibited good mechanical properties, a high absorption capacity and selectivity, and a high reusability (> 200 times) in oil-water separation. More importantly, the absorbed oil could be collected by simple squeezing. (C) 2014 Wiley Periodicals, Inc.
