20.500.12556/RUL-172908 Predobdelava s plazmo za izboljšanje kakovosti zlepljenosti lesnih in nelesnih materialov z izbranimi lepili Plasma pre-treatment to improve the quality of bonding of wood and non-wood materials with selected adhesives V diplomskem delu smo raziskovali vpliv obdelave površine z dielektrično barierno razelektritveno (DBD) plazmo na lepljivost lesa in nelesnih materialov. Preučevali smo, do kakšnih sprememb prihaja na površini materialov po obdelavi s plazmo DBD in vpliv teh sprememb na kakovost lepljenja. Parametre za obdelavo s plazmo smo določili na podlagi merjenja stičnih kotov na površini lesnih in nelesnih materialov. Po obdelavi s plazmo DBD smo površine vzorcev obdelanih in neobdelanih materialov preučili z laserskim mikroskopom in tehniko rentgenske fotoelektronske spektroskopije (XPS). Zlepljene vzorce obdelanih in neobdelanih materialov smo testirali po standardu SIST EN 205:2016 in tako ugotavljali njihovo natezno-strižno trdnost. Ugotovili smo, da površinska obdelava s plazmo DBD izboljša kakovost zlepljenosti z večino lepilnih sistemov, ki smo jih testirali v diplomskem delu. Plazemska obdelava je pri vseh materialih povečala površinsko energijo, predvsem polarni del, ki je ključen za dobro lepljivost. 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.
