Summary:

Centrifugal Adhesion Balance (CAB) is used for measuring directly solid-liquid work of adhesion by inducing an ever-increasing normal force which pulls on the droplet while keeping zero lateral force until the liquid-solid contact area starts to shrink spontaneously. Upon detachment of the liquid from the surface, the work of adhesion is then calculated based on Tate’s law. This method mimics a pendant drop that is subjected to a gravitational force that is gradually increasing. After describing the method, we will describe how the work of adhesion varies for different systems
