Porous materials with selective wettability and permeability have significant importance in oil-water separation

but complex fabrication processes are typically required to obtain the desired structures with suitable surface chemistry. In this work

an industrial melt-blown strategy that utilized commercially available polypropylene (PP) was used for the large-scale fabrication of superhydrophobic/superoleophilic membranes with staggered fabric structures. These membranes could readily separate different oils including pump oil and crude oil from various aqueous solutions such as strongly acidic

alkaline

and saline media. In addition

the separation efficiencies of these membranes exceeded 99%

and they could remain functional even after exposure to corrosive media. We anticipate that this work will further the design of membranes and enhance their applicability in oil-water separation

and provide researchers and engineers with a more effective tool for performing challenging separations and mitigating pollution.
