Low-pressure cold plasma surface treatment for adhesion improvement in composite structures

Popis výsledku v původním jazyce

The presented research uses the low-pressure cold plasma treatment for grafting of functional groups (e.g. hydroxyl, carboxyl) on the surface of polyethylene (PE), non-polar plastic, and investigates the contribution to adhesion towards polar materials (glass, metal). Plasma treated PE reaches joint strength with chrome and steel of 7.2 and 10.3 MPa respectively, samples frequently fail in the PE bulk. The results obtained with fine smooth metal substrates indicate minimal mechanical anchoring effect between materials, i.e. joint strength resulting from different (stronger) adhesion mechanisms activated by the surface treatment. Such results eliminate the need for geometric structuring of substrate surfaces for enhanced adhesion as frequently done in for e.g. rotational molding industry. Part of the research is the transfer of the experimental results from a laboratory device to an industrial device for surface treatment of powder materials in mass production. Applications using plastic powders may benefit from the new material surface properties, which can allow a formation of high-quality composite structures due to a significantly improved interfacial adhesion.
