What is hydrophobic? Print

Hydrophobe: (from the combining form of water in Attic Greek hydro- and for fear phobos) is the physical property of a molecule (known as a hydrophobe) that is repelled from a mass of water.


Hydrophobic is a property of some materials. A substance is called hydrophobic when it is water repellent or when it is not mixable with water. Hydrophobic literally means "water fearing". The cause of hydrophobicity is at the molecular acheter cialis generique level. Water is a polar compound which is attracted to other polar compounds. Between water and non-polar compounds there is no molecular attraction. Water repellent coatings are made of non-polar compounds. Water will not wet the material, but forms droplets that slide easily from the material. The opposite of hydrophobic is hydrophilic. A chemical compound with a hydrophobic and hydrophilic side is also known as amphiphilic.
