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 152.2° for water, and 0° 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.
