Chemical etching of fluoropolymers is a process used to selectively remove material from the surface using chemical solutions to improve wettability.
This difference in wettability is key in determining how each membrane is used.
Drop volume can have an effect on contact angles on certain surfaces.
Advancing contact angle is the highest possible contact angle measured on a previously unwetted solid surface.
Roughness corrected contact angle, is an angle where the effect of surface roughness is taken away.
Instead, one can measure static contact angles, advancing and receding contact angles, and roughness corrected contact angles.
For the mechanical performance of the composite, the adhesion between fiber and the matrix is of utmost importance.
Hydrophobic coatings are used in many consumers products. Contact angle measurements can be used to study them.
Anti-fogging coatings can be studied with contact angle measurements.
