Category — Hydrophobic Knowledge

Hydrophilicity, comes from the Greek ύδωρ, (water) and φιλία (friendship). It refers to a physical property of a material that can transiently bond with water (H₂O) through hydrogen bonding.

A hydrophilic material is a friend of water. Friends like to come closer, so a water droplet would spread on a hydrophilic surface. Furthermore water can enter the pores of a hydrophilic material and totally wet it. Most natural materials are hydrophilic.

The evaluation of hydrophilicity is made through water contact angle measurements. A water droplet would occupy as long surface of the hydrophilic material as possible. So the water contact angle will be significantly low.
