Abstract：In order to solve the existing problem of the poor corrosion resistance of the superhydrophobic materials, a novel type of copper mesh-based superhydrophobic materials with outstanding corrosion resistance was prepared and then was applied to the oil/water separation. The octadecylamine modified multi-walled carbon nanotubes was combined with the aminoethylaminopropyl polydimethylsiloxane(AEAPS) modified WPU and one-step spray method was adopted to prepare the copper mesh-based superhydrophobic surfaces with nest-like structure. The as-prepared mesh shows both superhydrophobic and superoleophilic properties simultaneously with a high water contact of 162° and an oil contact angle of 0°. Thus, they can be used to separate a series of oil/water mixtures, such as kerosene, toluene, tetrachloromethane, petroleum and hexane with separation efficiency above 93.79% and stable recyclability. In addition, the as-prepared mesh can maintain its superhydrophobic property after soaking in corrosive solutions (1mol/L NaOH, HCl, NaCl) for 24h.
