In this thesis, we researched the effects of DBD plasma surface treatment on the adhesion of wood and non-wood materials. We examined the changes that occur on the surfaces of the materials after DBD plasma treatment and the impact of these changes on the quality of bonding. The parameters for plasma treatment were determined based on the measurement of contact angles on the surfaces of wood and non-wood materials. After DBD plasma treatment, we analysed the surfaces of the treated and untreated samples using a laser microscope and XPS technique. We tested the bonded samples of treated and untreated composites according to the standard SIST EN 205:2016 to determine their tensile-shear strength. We found that the surface treatment with DBD plasma improves the properties of most adhesive systems tested in the thesis. Plasma treatment increased the surface energy for all materials, particularly the polar component, which is crucial for good adhesion.
