  • Publication number: 20240123118
    Abstract: A titanium superhydrophobic surface comprising a coating of a perfluorosilane on contiguous titania micrograins surrounded by crevices, the micrograins comprising a topography of nanopits shaped by contiguous peaks and valleys. The superhydrophobic surface has significantly increased hemocompatibility and enhanced antibacterial properties compared to an unmodified titanium surface. The increased hemocompatibility was confirmed by reduced platelet adhesion, reduced leukocyte adhesion, and reduced thrombus formation. The surface is prepared by a facile hydrothermal treatment of a titanium surface with sulfuric acid, leading to the formation of a unique micro-nano surface topography. The superhydrophobic surface was then achieved by coating the micro-nano titanium surface with a low energy silane using physical vapor deposition.
