kontaktvinkelmätning
Kontaktvinkelmätning, or contact angle measurement, is a technique used to characterize the wettability of a surface. It involves measuring the angle formed at the point of contact between a liquid and a solid surface. This angle is determined by the balance of interfacial tensions between the solid-liquid, liquid-vapor, and solid-vapor interfaces. A low contact angle, typically less than 90 degrees, indicates that the liquid spreads on the surface, signifying good wettability. Conversely, a high contact angle, greater than 90 degrees, suggests that the liquid beads up and does not spread, indicating poor wettability.
The measurement is typically performed by placing a small droplet of liquid on the solid surface and
