Hydrophobic surfaces are materials that repel water, preventing it from spreading or wetting the surface. This property is due to the molecular structure of the material, which often includes low-energy surfaces that do not interact well with water molecules. Common examples of hydrophobic surfaces include lotus leaves, which are known for their ability to shed water droplets, and certain coatings used in waterproof clothing. These surfaces are utilized in various applications, such as in self-cleaning surfaces and anti-fogging coatings. By minimizing water adhesion, hydrophobic surfaces can reduce the buildup of dirt and grime, making them easier to clean and maintain.
