Plasma treatment of polymer surfaces is widely used to improve the adhesion on the surface of work pieces. DataPhysics Instruments offers a simple and reliable method to characterise the surface treatment effect on polymers via contact angle measurement. Application experts from DataPhysics Instruments have defined surface free energy for four different polymers before and after surface treatment. They used ink method and optical method of contact angle measurement. Divergence in obtained results and high subjectivity of the ink method show that ink method does not always give the correct evaluation of surface activity of polymer. The contact angle measurement method and his advantages are described in this study as well.
