Abstract

Oily wastewater not only pollutes the environment seriously but also is difficult to separate. Herein, by spraying the polytetrafluoroethylene aqueous dispersion onto the cotton fabric, a superhydrophobic/superoleophilic cotton fabric (coded as SSCF) was prepared. The so-prepared SSCF could separate the stratified and emulsified oil with high separation efficiency (above 95.0%). Moreover, the SSCF possessed excellent durability under different conditions, such as abrasion, ultrasonication in ethanol, immersion in boiling (ice) water and different aqueous solutions of HCl (1M)/NaOH (1M)/NaCl (1M), and organic solvents (kerosene and toluene). These experimental results showed that the SSCF provided an effective method in oil/water separation.
