Influence of surface roughness on wettability and how to measure it
Many surface modification and coating technologies that are used for optimising wettability and adhesion properties influence both surface chemistry and roughness. Understanding the mechanisms that impact wetting and adhesion by separating these two factors can be key to successful surface development and solving of quality issues.
The Attension 3D Topography Module combined with Attension Theta Optical Tensiometer is the first product which makes it possible to combine 3D surface roughness measurements in conjunction with contact angle measurements. This makes it possible to perform those measurements on the same exact sample location. Roughness correction of contact angles also enables the calculation of fundamental surface free energy on rough surfaces. Download this white paper if you are interested in finding out more!
