Durable water repellent is a type of fabric coating to protect them from water. In addition, superhydrophobic coatings have potential uses in vehicle windshields to prevent rain droplets from clinging to the glass, to improve driving visibility. Rain repellent sprays are commercially available for car windshields. [14] [15]
Hydrophobe. 165 degree water contact angle on a surface modified using plasma technology system surface chemistry. The contact angle is the red angle plus 90 degrees. Dew drop on a hydrophobic leaf surface. Cutting a water droplet using a superhydrophobic knife on superhydrophobic surfaces. Water drops on the hydrophobic surface of grass.
Durable water repellent, or DWR, is a coating added to fabrics at the factory to make them water-resistant (hydrophobic). Most factory-applied treatments are fluoropolymer based; these applications are quite thin and not always effective. Durable water repellents are commonly used in conjunction with waterproof breathable fabrics such as Gore ...
Waterproof fabric. Waterproof fabrics are fabrics that are, inherently, or have been treated to become, resistant to penetration by water and wetting. The term "waterproof" refers to conformance to a governing specification [1] and specific conditions of a laboratory test method. They are usually natural or synthetic fabrics that are laminated ...
Water-repellent glass is often used to coat automobile windshields to increase visibility in rainy conditions. Water-repellent glass (WRG) is a transparent coating film fabricated onto glass, enabling the glass to exhibit hydrophobicity and durability. [1] WRGs are often manufactured out of materials including derivatives from per- and ...
Hydrophobic silica is a form of silicon dioxide (commonly known as silica) that has hydrophobic groups chemically bonded to the surface. The hydrophobic groups are normally alkyl or polydimethylsiloxane chains. Hydrophobic silica can be processed in different ways; such as fumed silica, precipitated silica, and aerosol assisted self assembly ...

A) A superhydrophobic surface with a high contact angle nearing 180 degrees. B) A surface with a low water sliding angle. C) A surface with a higher sliding angle which will be less efficient when self-cleaning water from its surface. Control over surface wettability is a critical aspect of self-cleaning surfaces.
