WebFeb 20, 2014 · In the scientific community, we have come to accept the definition that a surface is hydrophobic when its static water contact angle θ is >90° and is hydrophilic when θ is <90°. There is actually very little rationalization as why the surface switches from being hydrophilic to hydrophobic when θ changes only 2° from 89 to 91°. WebMar 25, 2024 · Main Differences Between Hydrophilic and Hydrophobic. Hydrophilic means having harmony with water or water-loving. On the other hand, Hydrophobic means resistance to wetting. Hydrophiles are the hydrophilic molecules, whereas hydrophobes are the hydrophobic molecules. Hydrophiles get dissolved or absorbed in water.

A hydrophilic molecule or portion of a molecule is one whose interactions with water and other polar substances are more thermodynamically favorable than their interactions with oil or other hydrophobic solvents. They are typically charge-polarized and capable of hydrogen bonding. This makes these molecules soluble not only in water but also in other polar solvents. Hydrophilic molecules (and portions of molecules) can be contrasted with hydrophobic molecule…
