WebSurface energy is, as you might expect, expressed in units of energy per area. Typically, it is measured in a unit called “dynes” where 1 dyne/cm is equal to 1 mJ/m. Most commonly, surface energy is measured with water. When a droplet of water is placed on a surface, it will bead up to some extent. Theoretically, if the surface energy is ... WebMar 15, 2024 · In adhesion testing, the top of the fabric specimen is attached to the upper jaws of the testing device and the loose film that has been manually separated from the substrate is attached to the lower jaws. The jaws are pulled apart with growing levels of force as to measure the point at which the film continues to peel away from the substrate.
