Material with super-oleophobicity under water and super-hydrophobicity under oil for oil-water emulsion separation and solvent-free preparation method thereof

The invention discloses a fibrous membrane with super-oleophobicity under water and super-hydrophobicity under oil for oil-water emulsion separation prepared by a solvent-free method. The method is characterized in that nano silica adsorbs Fe<3+> and then is assembled onto the surface of filter paper fibers, and then polypyrrole is deposited by gaseous polymerization. The obtained filter paper fibrous membrane has the functions of super-oleophobicity (OCA=165 degrees) under water and super-hydrophobicity (OCA=159 degrees) under oil, water-in-oil and oil-in-water microemulsions can be separated only under the action of gravity, the separation efficiency is 99%, and the flow rate is 300 L/m<2>/h. The method has the advantages that raw materials are cheap and easy to obtain, the preparation conditions are mild, and the gaseous polymerization not only avoids the use of solvent, but also uses fewer raw materials. In addition, the material is good in durability and can be recycled; the disadvantages that an existing filtered demulsification net membrane can only separate one type of oil-water emulsion and is poor in stability are overcome. The super-lyophobic fibrous membrane has broad application prospects in the fields of oil-water separation, especially emulsion separation, oil-containing sewage treatment and the like.
