What are the obvious advantages of superhydrophobic coatings

Super hydrophobic coating has been developed in recent years. Its use effect is very strong, and it can make water substances such as rain and snow isolate products. What are the obvious superior properties of super hydrophobic coating?Today let's have a look.

1.Self - cleaning function of superhydrophobic coating

If the outer wall of the building, outdoor billboards and so on, the surface of the object is like a lotus leaf, it can keep clean motor and other small parts can prevent oil and oil climbing car windscreens are no longer always full of dust and oil particles electronic digital products are not afraid of accidental fall into the water and damage, fabric is not easy to be polluted by dirt

2. Drag reduction function of super hydrophobic coating

When ships travel on the surface, they need to consume a lot of energy to overcome the frictional resistance during the journey, even for underwater vehicles like submarines, up to 80%.For transport pipelines, such as oil (water) pipelines, almost all of the energy is used to overcome frictional resistance on fluid-solid surfaces.With the development of mems, the size of the mechanism becomes smaller and smaller, and the friction force of the solid-liquid interface becomes larger and larger. Frictional resistance problems such as microchannel flow have become important constraints for the development of related devices.Therefore, minimizing surface friction resistance is the main method to improve speed and save energy.

Although the artificial preparation of superhydrophobic surface started late, it developed rapidly and its preparation methods became more and more effective, mainly including template method, electrostatic spinning method, phase separation method, self-assembly method, sol-gel method, etching method, hydrothermal method, chemical deposition and electrodeposition method, nano silicon dioxide method and corrosion method.
