    Which surface free energy method should be used?

    You might find it confusing when seeing all the different methods for surface free energy calculations. As surface free energy can give you more information on your surface compared to the contact angle measurements alone, it is time well spent to study the different theories more in detailed.

    What is contact angle?

    Contact angle is the angle a droplet forms in contact with a solid surface. Thermodynamically, it is a balance between cohesive and adhesive forces.
