Hydrophobic surface and its application to drag reduction

In this paper, the principles of hydrophobic surface and drag reduction are outlined. We briefly review the new way and recent progress to prepare such hydrophobic surface. The latest advance of hydrophobic surface research on drag reduction and weakness of such surface are mentioned. The paper points out that anti-drag hydrophobic surfaces with the properties of hydrophobic, wearable, corrosion resistant and good bonding strength can be prepared by adopting vapor deposition combined with in situ reactive infiltration, etc.
