A novel composite coating mesh film for oil/water separation

摘要：

In this article, polytetrafluoroethylene (PTFE) polyphenylene sulfide (PPS) composite coating mesh film was successfully prepared by a simple layered transitional spray-plasticizing method on the stainless steel mesh. This composite coating mesh film holds the excellent properties of PTFE and PPS. Whats more, it shows super-hydrophobic and super-oleophilic properties. The contact angle of this mesh film is 156.3 ° for water, and close to 0 ° for diesel oil and kerosene.The contact angle hysteresis of water on the mesh film is 4.3 ° . The adhesive force between mesh film and substrates is grade 0, the flexility is 1 mm and the pencil hardness is 4H. Furthermore, the corrosion resistance and the stability in the atmosphere of PTFE -PPS composite coating mesh film are perfect. The film was used to oil/water separation, which showed good separation effect. So it would be expected for industrial application.
