In our fourth edition of the Tensiometry Masterclass Series, we will focus on manual tilting contact angle measurements featuring the Theta Lite optical tensiometer. Dynamic contact angle and roll-off angle determined from droplet tilting are a useful way to characterize the performance of different surfaces or coatings, such as anti-fog, self-cleaning, superhydrophobic, or antimicrobial. In this masterclass, we will go through a dynamic contact angle measurement with the manual tilting stage and measure advancing and receding contact angle as well as roll-off angle. We will focus on how to properly set up and operate the tilt stage as well as capture the tilted contact angle in OneAttension.
