Assessing the Accuracy of Contact Angle Measurements for Sessile Drops on Liquid-Repellent Surfaces

Gravity-induced sagging can amplify variations in goniometric measurements of the contact angles of sessile drops on super-liquid-repellent surfaces. The very large value of the effective contact angle leads to increased optical noise in the drop profile near the solid–liquid free surface and the pr...
