Due to the broad application prospects in the industry (such as oil transportation, oil storage, oil crawling, etc.), super-hydrophobic / super-oleophobic surfaces have been a hot field in the field of surface functional materials in recent years. However, it is still a prominent difficulty in this field to widely superoleophobic, especially various low surface energy liquids, and there are few related reports at present.
The research team led by Researcher Zhou Feng and Researcher Liu Weimin from the State Key Laboratory of Solid Lubrication, Lanzhou Institute of Chemical Physics successfully prepared ultra-double phobic surfaces on the surface of engineering materials aluminum and its alloys by simple and rapid electrochemical reactions combined with surface modification methods , The surface can be ultra-sparse including water, edible oil, ionic liquids, organic solvents, organic alkanes, polymer melts and other non-fluorine-containing liquids, especially for aviation lubricants and crude oil show ultra-low adhesion , It also has anti-wax properties. This result has been published as a hot article in the internationally renowned journal "ChemCommun" (ChemCommun), the most important thing is that the coating material's very strong application background is not only reflected in its excellent super double phobic performance, but also in the preparation method It is a traditional process with low cost and easy operation. At the same time, on the basis of this work, they also successfully prepared polyurethane super-double-phobic coatings and other polymer-based super-double-phobic materials by template replication.
