can be used to activate a surface which increases its surface energy, but how can you tell how much energy a surface has? One test to measure surface activation is to compute the contact angle
that a drop of water creates on a surface. The larger the angle that the drop of water creates with the surface, the less surface energy it has, meaning low adhesion capabilities. Materials that have been thoroughly activated should have a very low, almost zero, contact angle
. This indicates that the surface has a high adhesion potential. When you need an exact quantification of surface activation
, contact angle measurements
are the most precise way to calculate a surface’s adhesion capability.
