Research Progress of Superhydrophobic Coatings Constructed by Arrayed and Non‐arrayed Carbon Nanotubes for Anti‐corrosion, Anti‐icing and Photothermal De‐icing

Abstract: The preparation methods of superhydrophobic nanocomposite surfaces based on carbon nanotubes are reviewed in view of the different arrangement accuracy and various performance differences of the preparation methods of superhydrophobic surfaces of arrayed and non‐arrayed carbon nanotubes. The application progress of superhydrophobic surfaces of non‐arrayed carbon nanotubes in the fields of anti‐corrosion, anti‐icing and photothermal de‐icing is introduced. On the basis of summarizing the basic preparation methods and properties of carbon nanotubes, the advantages of carbon nanotubes as superhydrophobic surface materials are clarified. By analyzing and comparing the preparation methods of superhydrophobic surface of arrayed carbon nanotubes and non‐arrayed carbon nanotubes, it is concluded that the superhydrophobic surface of arrayed carbon nanotubes has some shortcomings compared with the superhydrophobic surface of non‐arrayed carbon nanotubes. The superhydrophobic surface of non‐arrayed carbon nanotubes offers advantages such as excellent long‐term durability and unique functionality, which will become the focus of research on the preparation of superhydrophobic surfaces based on carbon nanotubes. This will provide guidance for future research on the large‐scale preparation of such surfaces.
