According to media reports on June 30, American researchers have recently invented a super waterproof material that improves the waterproof performance by adding tiny columns or rails to the surface of the coating. The water droplets on the contact surface can not only stay away but can rebound.

The inventor of this technology is Julie Crockett, a professor of mechanical engineering at Brigham Young University in Utah, and her colleague Professor Dan Mains. Professor Crockett said that they can be turned into "super waterproof" materials by building this structure on existing waterproof materials such as wax and polytetrafluoroethylene.

Inspired by the lotus leaf, scientists have discovered a permanent waterproofing method: the surface of the coating is treated with a tiny structure to obtain a "super waterproof" surface material suitable for all items.

Scientists have observed this structure of the lotus leaf so that the water droplets can stay on it and not lose shape. Inspired by this, a waterproof material with pillars, rows and holes on the surface was developed. When the water droplets touch the surface of this material, they are scattered first, and then gathered together due to the existence of this tiny structure. The tension between the water molecules is stronger than the tension between the water molecules and the surface of the material, causing the water droplets to break off the surface of the coating directly after polymerization, bouncing high.
