Detailed explanation-1: -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.

Detailed explanation-2: -Hydrophobic materials are those based on the chemical concept of hydrophobicity, i.e. the ability of the substance to repel water. Hydrophobicity is a term derived from the Greek “hydro”, meaning water, and “phobos”, meaning fear.

Detailed explanation-3: -Hydrophobic literally means “the fear of water”. Hydrophobic molecules and surfaces repel water. Hydrophobic liquids, such as oil, will separate from water.

Detailed explanation-4: -According to these straight definitions, we can see that these two terms are opposites. Something defined as hydrophilic is actually attracted to water, while something that is hydrophobic resists water.

Detailed explanation-5: -Hydrophobic Means “Fear of Water": Hydrophobic molecules repel water because they are generally non-polar molecules. As water is a polar molecule, hydrophobic molecules tend to interact with each other instead of with water.
