东方德菲仪器：使用一种液体检测聚合物膜的润温性能

The OCA20 offers an easy way of determining the surface energy of polymer 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﹪.
