Abstract:Extreme wettability materials have shown great ability in dealing with oily industrial wastewater emission and oil spill accidents. Whenas, most of the addressed materials are technically sophisticated or inclined to involve corrosive or toxic chemicals. Herein, we fabricated an easy fabricated, low cost and robust material for oil/water separation. The superhydrophobic-superoleophilic (SOO) cement-coated meshes were made simply by dipping copper mesh in cement paste and surface modification. The micro/nanostructure and low surface energy endowed the mesh with great superhydrophobicity and superoleophilicity in air. The mesh had great oil absorption ability and high separation efficiencies for various oils. They were also admirably recyclable and durable. The meshes could be used to separate oil/water mixture at least for 20 cycles with high separation efficiency, and showed respectable superhydrobocity after being bent for 30 times. This simply fabricated, low cost and robust material will have great potential to be used in industrial wastewater treatment and oil spill in seawater.
