Contact Angle Fundamentals: What You Actually Need to Know

WebIn a contact angle measurement, the angle between the droplet and solid surface indicates the wettability of the surface. In surface science, an instrument called a contact … WebContact angle is one of the common ways to measure the wettability of a surface or material. Wetting refers to the study of how a liquid deposited on a solid (or liquid) substrate spreads out or the ability of liquids to form boundary surfaces with solid states. WebUsing the Bikerman equation, the contact angle of a sessile drop can be measured from above.
