Status of Fabrication Methods of Superhydrophobic Coatings Based on Metals

Metal corrosion not only brings huge economic loss, but also affect our personal safety and security, therefore, it is imperative to take effective measures for protection of metal corrosion. Due to the good performance of superhydrophobic coatings in protection of metal corrosion, the fabrication techniques including hydrothermal method, sol-gel method, electrochemical deposition, solution impregnation deposition, self-assembly method, chemical (electric) etching method, grafting polymerization method and template method were mainly introduced in this paper. Advantages and disadvantages of different kinds of techniques were discussed. And the developments direction in this field was prospected.
