Detailed explanation-1: -What is Hydrophilic? Hydrophilic means having an affinity for water.

Detailed explanation-2: -Hydrophilic (biology definition): water-loving; having an affinity for water; capable of interacting with water through hydrogen bonding. Etymology: from Greek hydros, meaning “water” and philia, meaning “friendship”. Compare: hydrophobic. Hydrophilic substances are polar in nature.

Detailed explanation-3: -If the droplet spreads, wetting a large area of the surface, then the contact angle is less than 90 degrees and that surface is considered hydrophilic, or water-loving (from the Greek words for water, hydro, and love, philos).

Detailed explanation-4: -Substances dissolving readily in water are called hydrophilic compounds. They consist of ions or polar molecules that use electrical charge effects to attract water molecules. The water molecules surround these polar molecules and carry them into the solution, thereby dissolving them.

Detailed explanation-5: -Hydrophilic refers to having a strong affinity for water. Something that is hydrophilic is soluble in water and dissolves into water very easily. Hydrophilic is the opposite of hydrophobic. Hydrophilic and hydrophobic surfaces both have important applications in all types of engineering, including: Chemical.
