In chemistry, hydrophobicity is the chemical property of a molecule (called a hydrophobe) that is seemingly repelled from a mass of water. [1] In contrast, hydrophiles are attracted to water.

2014年2月20日 · The most recognizable definitions in surface science are hydrophobicity and hydrophilicity. In the Greek words, hydro means water, philicity means affinity, and phobicity means lack of affinity.

In terms of thermodynamics, the hydrophobic effect is the free energy change of water surrounding a solute. [3] A positive free energy change of the surrounding solvent indicates hydrophobicity, whereas a negative free energy change implies hydrophilicity.

2013年7月16日 · Materials with a special affinity for water — those it spreads across, maximizing contact — are known as hydrophilic. Those that naturally repel water, causing droplets to form, are known as hydrophobic.

Hydrophobic interactions are involved in and believed to be the fundamental driving force of many chemical and biological phenomena in aqueous environments. This review focuses on our current understanding on hydrophobic effects.

2022年6月16日 · Hydrophobic means lacking an affinity for water; insoluble in water; repelling water. Examples of hydrophobic molecules include alkanes, oils, fats, and greasy substances in general. Compare: hydrophilic. Various hydrophobic substances can be found in both the domestic and industrial sectors.

Hydrophobicity or hydrophobic strength (also referred to as hydrophobic retentivity) of a stationary phase relates to the overall strength of dispersion forces between a nonpolar, nonionic solute and the stationary phase.

Hydrophobicity refers to the relative tendency of a substance to prefer a nonaqueous environment over an aqueous one. It is a key physico-chemical property often used in various scientific disciplines such as drug design, toxicology, and environmental monitoring.

At the molecular scale, the term hydrophobicity is defined as the association of non-polar groups or molecules in an aqueous environment which arises from the tendency of water to exclude non-polar molecules (IUPAC; Compendium of Chemical Terminology, 1997).

Hydrophobicity is the physical property of a molecule or substance that causes it to repel water. It is a fascinating phenomenon with diverse applications, from designing water-repellent clothing to creating microfluidic devices.
