The invention discloses an oil-water separation
pipe with a hydrophobic and oleophylic surface and a preparation method and application thereof. The oil-water separation
pipe comprises a
metal net substrate, a conical array constructed on the
metal net substrate and made of
epoxy resin and
copper-containing nanorods wrapping the surface of the conical array, the conical height of the conical arrayranges from micron to
millimeter, the distance between every two adjacent cones ranges from microns to millimeters, and the surface of the oil-water separation
pipe is hydrophobic. The oil-water separation pipe material with the hydrophobic and oleophylic surface does not contain toxic and harmful substances, and is
environmentally friendly, easy to clean, capable of being repeatedly used and good in stability. When
emulsion separation of surfactant-containing
oily wastewater is carried out, the method has the advantages of good
emulsion separation effect on surfactant-coated micron-sized oildrops, high separation speed, high oil-water separation efficiency, continuous separation, low cost, low
energy consumption, no need of adding other chemical reagents and the like.
