To create an implant of the circulatory system using materials of different origin. The main requirements for such materials: rapid adaptation to the body and a long service life. Important characteristics are the hydrophobicity and surface roughness. Surface modification of materials by coating is the most common way to increase the functional properties. The study consisted in finding the perfect combination of the coating material and the technology of its application to the polyurethane product to increase its service life. In this study, we were applied two different methods of carbon coatings, which do not require heating of the polyurethane substrate: the method of laser deposition in a vacuum magnetron vacuum deposition method, and the pulverization of fine colloidal solution. Pulverization method applied to colloids with different powder: carbon nanotubes (CNT) and highly oriented pyrolytic graphite (HOPG), titanium oxide. Visualization of the surface produced on the optical, scanning electron and atomic force microscopy. Out of the samples, the most hydrophobic properties of the coated, fine colloidal solution HOPG caused by pulverization.
