Hydrophobic: meaning, definitions and examples

Typically used in scientific or technical fields to describe substances that do not mix well with water. It is often seen in chemistry and biology contexts.

• The hydrophobic tails of phospholipids align away from water in the cell membrane
• Certain proteins have hydrophobic regions that help them function properly

Commonly used in everyday language and industry to describe materials or surfaces designed to resist water penetration. This term is often used in the context of fabric, clothing, and outdoor gear.

• These shoes are water repellent, making them perfect for rainy weather
• The water repellent coating on the jacket kept me dry during the storm

Primarily used in chemistry to describe molecules that do not have a separation of electrical charge, which results in no positive or negative poles. It is often used in the context of chemical bonding and molecular interactions.

• Methane is a nonpolar molecule because the electrons are evenly distributed
• Nonpolar solvents are commonly used to dissolve nonpolar substances

Used in scientific or technical discussions to describe substances or surfaces that repel water.

• The coating on this jacket is hydrophobic, keeping you dry in the rain.
• This material is hydrophobic, making it ideal for water-resistant applications.
