surfaces. For the case of serial examinations on the same, only slightly modified
materials as they often occur in industrial production, a method has been
developed which further facilitates the determination of the surface energy.
Here, the measurement of a contact angle with just one liquid is needed,
thus considerably reducing the time needed. The example of PP films,
which were submitted to different surface treatments, showed that the new
method can predict the surface energy with an accuracy of 2﹪.
