BIOMOLECULES AND ENZYMES

Detailed explanation-1: -If a product is labeled as “water-repellent”, it means that it is hydrophobic, or repels water on contact. A feature of water-resistant and waterproof fabrics, water repellency measures how much water pressure a material can withstand before amounts of water begins to permeate.

Detailed explanation-2: -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-3: -A hydrophobic surface is one which will repel water, meaning they do not easily become wetted when in contact with water. This makes such a surface water resistant. “Hydrophobicity” was derived from two Greek words that are hydro (meaning water) and phobos (meaning fear).

Detailed explanation-4: -This attribute can be applied to a surface by cleaning, activating or by coating it with a thin hydrophilic layer. Hydrophilic coatings are polarized which is why they are attracted to water, which is also polar, whereas hydrophobic coatings are non-polar, which is why it will repel water.
