| Abstract: | In this study, the impact of a plasma treatment using dielectric barrier discharge at atmospheric pressure on wax-treated
beech was investigated by surface energy determination and adhesion tests. Measurements of the surface energy revealed a strong
increase in surface polarity along with increased surface energy as a result of the plasma treatment, pointing to increased
adhesion properties. To evaluate the adhesion properties of a polyvinyl acetate (PVAc) adhesive on beech treated with montan
ester wax and synthetic Fischer–Tropsch wax, a special peel test was applied. This peel test provided evidence of increased
adhesion of the PVAc after plasma treatment of both materials investigated. |
