Web26 mei 2024 · Hydrophobicity is a term derived from the Greek “hydro”, meaning water, and “phobos”, meaning fear. Hydrophobic substances are composed of non-polar molecules that repel bodies of water and attract other neutral molecules and non-polar solvents. Examples of these molecules are alkanes, oils and fats in general.

WebSuperhydrophobic surfaces have applications in many different industrial fields. Examples vary from water-repellent fabrics in the textile industry to self-cleaning windows and anti-icing coatings. As per definition, superhydrophobicity is achieved when the static contact angle with water is over 150° and the contact angle hysteresis (glossary) is low.
