    Superhydrophobic surfaces

    ~ 14 min

    What are Superhydrophobic Surfaces?

    Understand how superhydrophobic surfaces are defined, how they work, and how to measure them using contact angle methods. Explore key industrial applications—from self‑cleaning and anti‑icing to drag reduction—and what to consider when evaluating durability.

    Comparison of contact angle measurements on superhydrophobic surfaces

    Advancing and receding angles should be measured as the low contact angle hysteresis is also a requirement for superhydrophobicity.

    What does self-cleaning mean?

    A self-cleaning surface is any surface with the ability to readily remove any dirt or bacteria on it. Self-cleaning surfaces can be divided into three different categories; superhydrophilic, photocatalytic and superhydrophobic.

    How to make better blood-repellent surfaces?

    Blood-repellent surfaces are needed in medical devices that come in contact with blood. The traditional approach has been the use of antithrombotic surface treatments However, these coatings are prone to eventually wear-off. Superhydrophobic surfaces have been proposed as an alternative solution.
