“…After the shortest applied treatment duration of t D = 0.25 s a significant change on WPC is obtained with no further change of WCA, whereas on particle and fibre boards an exponential decrease in WCA is observable. The behaviour of WPC is in accordance with results obtained from plasma treated polymers 22. On pure wooden surfaces no further change of WCA is observable after a few seconds of plasma treatment 23.…”

In this study, the influence of a dielectric barrier discharge (DBD) at atmospheric pressure on wood plastic composites (WPC), particle board and fibre boards is investigated by means of contact angle measurements. The water contact angle (WCA) is determined and offers a possibility to detect changes of surface properties by plasma treatment. The surface energy divided into disperse and polar part is determined before and after plasma treatment. To estimate the adhesion, the work of adhesion between substrates and four different cured coatings is evaluated. It is shown that surface energy, primarily the polar part, is increased considerably by the plasma treatment. In addition, by the increased work of adhesion an enhanced adhesion is expected, which is confirmed by cross‐cut tests.

Continuous Electric Sorting in the Recycling Process of PlasticsThe continuous electric sorting is a process to separate mixed plastics in dry state with relatively little expenditure of energy. However, the electro-static charging, which is the basic requirement for specific separation, is a physical phenomenon of high complexity. An overview is given of the state-of-the-art of science about the electrostatic charging of plastics.Examples from practice are then employed to demonstrate to control of charging and separation processes.

“…The activation seems to enhance subsequent interdiffusion of polymer chains or the formation of interphases with superior mechanical properties in comparison to the bulk properties of the adhering partners. Different mechanisms of activation, which are discussed, are as follows [24]:…”
