Abstract: Plasma treatment of polymeric materials is a promising method of modifying surface properties. In particular, under the influence of gas plasma, the polymer structure is changed and a carbonized surface layer is formed, which affects the surface energy, relief texture and other surface properties. In this way, biomedical characteristics (sorption of proteins, decrease of bacterial adhesion) could be improved. However, external mechanical loads associated with the use of soft polymers can cause damage of the modified surface. These defects reduce the positive effect of plasma treatment. In this paper, the influence of low-energy plasma implantation of nitrogen ions (energies 0.1 and 0.5 keV) on the surface properties of elastic polyurethane is investigated. As a result of the treatment, the hydrophobicity and surface stiffness increase. However, in comparison with the higher plasma energy (at least 1 keV), the damage of the stretched material surface does not occur.
