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.
With increasing understanding of the superhydrophobicity, the measurement methods to quantify the degree of hydrophobicity deserve some thought.
This video will explain two main methods for measuring dynamic contact angle.
Superhydrophobic surfaces were an instant hit in the scientific community when they were introduced over two decades ago
The non-wetting surfaces have experienced an enormous boost of interest after the observation of superhydrophobicity and self-cleaning effect in natural lotus leaves.
