AbstractA superhydrophobic and superoleophilic gamma-AlOOH membrane on stainless steel mesh was fabricated by an inexpensive, template-free hydrothermal method using Al(NO3)(3)center dot 9H(2)O and Na2C2O4 as starting materials. A novel gamma-AlOOH film with a grass-like structure was synthesized and grass-like grains were tightly connected to form a hierarchical microstructure, which created a rougher stainless steel mesh surface. The influences of the additive amount of Na2C2O4 and Al(NO3)(3)center dot 9H(2)O on morphology and water contact angle of products were discussed. The prepared film is superhydrophobic not only for pure water but also for corrosive water under acidic or alkaline conditions. The obtained superhydrophobic and superlipophilic coated mesh exhibited high efficient oil/water separation. Besides the maximum diesel-water separation efficiency reach 99.6%, a high water intrusion pressure value of 2.2 kPa is also calculated, which make it promising application in large-scale, high-efficient and reusable oil/water separation filed.
