Contact angle measurement device for determining surface energy, hydrophobicity, and wettability of solid samples.
DSA100 / DSA 30 Krüss
The device dispenses droplets of liquids, such as water and diiodomethane, onto the surface under investigation. By capturing and analyzing the shape and contact angle of these droplets the instrument assesses surface energy and wettability. Contribution of the polar, apolar and van der Waals forces can be assessed.
The analysis yields critical data on how liquids interact with a material’s surface, aiding in the optimization of products like coatings, adhesives, and water-resistant fabrics. Understanding these interactions is essential for improving product performance and durability.
A newly developed self-assembled monolayer is used to render the surface of a polymer foil hydrophilic. Contact angle measurements are carried out to identify the performance of different deposition techniques.
