Hydrophobe

Drops of dew on grass in the morning

Hydrophobe is a term from chemistry for a substance that does not mix with water. Examples of such substances are different types of vegetable oils, and fats. Many hydrophobic substances are lipophiles, they mix with fats and oils easily.

A liquid droplet rests on a solid surface and is surrounded by gas. The contact angle, θC, is the angle formed by a liquid at the three-phase boundary where the liquid, gas, and solid intersect.
A droplet resting on a solid surface and surrounded by a gas forms a characteristic contact angle θ. If the solid surface is rough, and the liquid is in intimate contact with the solid asperities, the droplet is in the Wenzel state. If the liquid rests on the tops of the asperities, it is in the Cassie–Baxter state.
