摘要	Highly porous activated carbon with a large surface area and pore volume was synthesized by KOH activation using commercially available activated carbon as a precursor. By modification with polydimethylsiloxane (PDMS), highly porous activated carbon showed superhydrophobicity with a water contact angle of 163.6°. The changes in wettability of PDMS- treated highly porous activated carbon were attributed to the deposition of a low-surface-energy silicon coating onto activated carbon (confirmed by X-ray photoelectron spectroscopy), which had microporous characteristics (confirmed by XRD, SEM, and TEM analyses). Using an easy dip-coating method, superhydrophobic activated carbon-coated sponges were also fabricated; those exhibited excellent absorption selectivity for the removal of a wide range of organics and oils from water, and also recyclability, thus showing great potential as efficient absorbents for the large-scale removal of organic contaminants or oil spills from water. Supersponge, save the world! Superhydrophobic activated carbon-coated sponges show good selectivity, recyclability, and absorbencies ranging from 2695 to 8586 wt % for a wide range of organic solvents and oils. These materials may have useful applications especially in the fields of oil-spill cleanup and water treatment. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
