Research on engineering materials superphobic coating materials has made progress

Thread Content

The Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, recently successfully prepared a superamphiphobic surface on the surface of engineering materials aluminum and its alloys through a simple and rapid electrochemical reaction combined with surface modification methods for the first time. The surface can be superphobic to various non-fluorinated liquids including water, edible oil, ionic liquids, organic solvents, organic alkanes, polymer melts, etc. It especially shows ultra-low adhesion to aviation lubricants and crude oil, and also has anti-waxing properties. The preparation method of the coating material is a traditional process, which is low cost and easy to operate. In addition, the institute has also successfully prepared polyurethane superamphiphobic coatings and other polymer-based superamphiphobic materials using template replication methods. It is understood that superhydrophobic/superoleophobic surface functional materials are a hot research field, and superoleophobicity has always been a prominent difficulty in this field.
