Hello

Have you tried to look contact angle mesurement?

Laurène Youssef, I have come to understand that variations in contact angle to some extent reflect the variations in the magnitude of these forces. However it does not give a direct figure of quantification. Unless there is something I have been missing all along?

Hello

There are many formula that could help you calculate and quantify the forces using contact angle technique.

Here you can find a review about it:
