Highly hydrophobic and oleophilic foam for selective absorption
In this article, both highly hydrophobic and oleophilic foam were fabricated by coating inner surface of polyurethane (PU) foam with a super-hydrophobic film. The contact angle of the foam is large as 152.28 for water, and 08 for kerosene. The foam can absorb kerosene selectively from kerosene-water mixture and be regenerated easily. The foam may be used to reclaim oil from polluted natural water area resulted from shipwreck or leakage. (C) 2009 Elsevier B.V. All rights reserved.
