In chemistry, hydrophobicity is the physical property of a molecule that is seemingly repelled from a mass of water (known as a hydrophobe). In contrast, hydrophiles are attracted to water. Hydrophobic molecules tend to be nonpolar and, thus, prefer other neutral molecules and nonpolar solvents. Because … Meer weergeven The hydrophobic interaction is mostly an entropic effect originating from the disruption of the highly dynamic hydrogen bonds between molecules of liquid water by the nonpolar solute forming a clathrate-like … Meer weergeven Dettre and Johnson discovered in 1964 that the superhydrophobic lotus effect phenomenon was related to rough hydrophobic surfaces, and they developed a theoretical … Meer weergeven • Amphiphile – Hydrophilic and lipophilic chemical compound • Cerium(IV) oxide – chemical compound • Contact angle meter – Angle measuring instrument Meer weergeven Superhydrophobic surfaces, such as the leaves of the lotus plant, are those that are extremely difficult to wet.

WebHe suggests that superhydrophobicity must have evolved 450 million years ago when life moved onto land and started respiring via gas exchange. ‘We have looked at about 24,000 different species of plants and animals and many of them are superhydrophobic or at least have superhydrophobic parts,’ he says. Many extrude a crystalline waxy layer. The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in an aqueous solution and exclude water molecules. The word hydrophobic literally means "water-fearing", and it describes the segregation of water and nonpolar substances, which maximizes hydrogen bonding between molecules of water and minimizes the area of contact between water and non…
