Effects of plasma treatments and temperature on the triboelectric charging behavior of polymers in stirring and shaking charging processes — •Alina Bachmann — Frankfurt am Main, Hessen, Germany

This study evaluates the triboelectric charging behavior of polymers. Examining the effect of different plasma pretreatments and temperatures, the saturation charging of various multi-component polymer blends was conducted.

Within the experimental procedure, the saturation charge through stirring and shaking charging processes was compared. The charge-to-mass ratio and surface charge density serve as crucial parameters for characterising the treated surfaces.

The results of the study find application in the electro-sorting of plastics based on triboelectricity. Since this phenomenon is not scientifically understood to a full extent, the generated data contributes to a more optimised implementation in the technical field.
