Contact angle measurement device for determining surface energy, hydrophobicity, and wettability of solid samples.
Equipment
DSA100 / DSA 30 Krüss
Method
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.
Expected Result
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.
Case Study
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.
UV-Vis/NIR spectrometer for analyzing transmission, reflection, and absorption of solid and liquid samples. Ideal for optical material characterization in research and development.
The tensile testing machine enables precise measurement of tensile strength, elongation and modulus of elasticity of a wide range of materials in research, development and quality control.
