Abstract
Diffuse coplanar surface barrier discharge (DCSBD) is an innovative plasma source that finds application in industrial practice and also in the surface treatment of various types of materials. The presented paper deals with the investigation of structural changes in selected thermoplastic materials that have occurred after their treatment with plasma discharge. The structural changes were investigated by using dynamic mechanical analysis, where the changes between the unmodified material samples and the thermoplastic material samples exposed to the plasma discharge, were compared, based on the obtained data of the storage modulus, the loss modulus and the loss tangent. For the experiment, thermoplastic materials were chosen, which are widely represented in the production of packaging materials, namely polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET).
