Abstract (EN): Adhesion between rubber and leather is a crucial factor in the footwear industry. In the present work, three types of vulcanized styrene-butadiene rubbers (SBR) were modified using optimized atmospheric plasma jet treatment. Adhesion strength of SBR samples to leather, bonded by polyurethane (PU) adhesive, was evaluated and the ageing effect was studied. Plasma-treated rubbers were subjected to air ageing to evaluate the extent of hydrophobic recovery and the effect on the joint strength. Joint strength of the modified samples was evaluated by the T-peel test. The plasma treated surfaces were analyzed by means of contact angle measurements and scanning electron microscopy (SEM). The atmospheric plasma surface treatment significantly improves the wettability as well as adhesion of SBR. The ageing study showed a partial hydrophobic recovery of only one type of SBR, but the strength of adhesively-bonded joints between SBR surfaces and PU adhesive did not correspond with the ageing of plasma treatment.
