© 2016 The Royal Society of Chemistry. A new alkyl-pyrene has been synthesized and is used to modify multiwall-carbon nanotube to form films that are both superhydrophobic and superoleophilic. The superhydrophobic property of the MWCNT films prevents water from going through and the superoleophilic property of the films attracts oil, facilitating it to pass through the MWCNT filtration films. This film can also be easily recycled to prepare brand new water-oil separation filters and can be easily scaled up for large sizes. Our results reveal that the modified MWCNT film prepared here is a promising candidate for use in removal of oils and other organic pollutants from water.
