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. … Ver mais 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 structure around … Ver mais Dettre and Johnson discovered in 1964 that the superhydrophobic lotus effect phenomenon was related to rough hydrophobic … Ver mais • Amphiphile – Hydrophilic and lipophilic chemical compound • Cerium(IV) oxide – chemical compound • Contact angle meter – Angle measuring instrument • Froth flotation – Process for selectively separating of hydrophobic materials from hydrophilic Ver mais Superhydrophobic surfaces, such as the leaves of the lotus plant, are those that are extremely difficult to wet.
