For the oil-in-water (O/W) emulsion separation, a 0.3 μm Al 2O 3 particle layer was used. The particle layer has the property of underwater superoleophobicity after prewetting. A porous layer was fabricated by superhydrophilic Al 2O 3 particles, which could separate oil–water emulsions. This paper proposes a simple method without other modifications for separating the oil–water emulsion. The coatings used may lack adequate surface mechanical and chemical durability. The separation of oil–water emulsion using superliquiphobic/philic porous coated materials has attracted considerable attention for dealing with environmental pollution and resource recycling issues.
