Detailed explanation-1: -Having an affinity for water. A membrane which will wet with aqueous (water) solutions. Hydrophilic membranes are generally chosen for use with aqueous solutions.

Detailed explanation-2: -Materials and molecules that have an affinity for water are hydrophilic; a hydrophilic surface will cause water to spread, and molecules that are hydrophilic tend to dissolve well in water.

Detailed explanation-3: -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.
