WebA hydrophilic uncharged surface is considered to be resistant to fouling. Any chemical coming in contact with the membrane may alter the membrane surface by attaching or detaching some functional moieties, possibly bringing a change in the hydrophilicity and surface charge. 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 water molecules are polar, hydrop…
