This paper present the issue of plasma treatment of the surface of polypropylene (PP) using AgO+CuO coatings in order to antimicrobial activity. The analyzed coatings were deposited using High Power Impulse Magnetron Sputtering (HPIMS). This method is characterized by high power density, high ionization and high plasma density, which enables the production of high-quality multi-component coatings. All CuO+AgO coatings, formed on the polypropylene (PP) surface by MS-PVD magnetron sputtering with various parameters, were tested in terms of morphology, chemical composition, mechanical properties and antibacterial properties. The conducted analysis showed a significant influence of the chemical composition on the structure, density and mechanical properties of the obtained coatings. The analysis of the continuity of structure different CuO+AgO coatings showed that its depending on chemical composition. Furthermore, different growth mechanism of the coatings are observed. It was also found that plasma treatment of polypropylene (PP) with CuO+AgO layers allows to provide good antimicrobial properties.
