This method mimics a pendant drop that is subjected to a gravitational force that is slowly increasing until the solid–liquid contact area starts to shrink spontaneously. The work of separation is then calculated in analogy to Tate’s law. The values obtained for the work of separation are independent of drop size and are in agreement with Dupré’s theory, showing that they are equal to the work of adhesion. %I ACS Publications
