Sessile drop measurement is the most commonly used contact angle measurement method. In practice, a droplet is placed on the solid surface and an image of the drop is recorded. The static contact angle is then defined by fitting Young-Laplace equation around the droplet, although other fitting methods such as circle … See more Dynamic contact angle measurements with the optical tensiometer are done with two main methods: needle method and tilting method. In the … See more Roughness corrected contact angles are measured with the combined surface roughness and contact angle measurements. The … See more

Influence of droplet volume on contact angle

WebThe static contact angle is normally defined as the average value of various contact angle measurements. However, this can lead to great errors due to the irregularity of the real surface. The dynamic contact angles are the … WebTheta Lite is a compact and accurate contact angle meter for simple measurements of contact angle andsurface free energy.
