wettability / contact angle analysis
Wettability and contact angle can be measured.
The wettability of a liquid is how much it spreads over the surface of a particular solid, measured by the flatness of a droplet on the solid surface.
One of the major methods, the static drop method is used to measure contact-angle of the droplet to the surface.
One of the major methods, the static drop method is used to measure contact-angle of the droplet to the surface.
Features of extruded liquid drop method
- Fresh droplet can be used.
- Droplet size can be changed arbitrarily.
- Advancing /Receding contact angles can be measured.
