Surface modification of blood-contacting biomaterials by plasma-polymerized superhydrophobic films using hexamethyldisiloxane and tetrafluoromethane as precursors

•Biomaterials modified by nanoparticle-containing plasma polymerized films.•A superhydrophoic film was obtained, and the properties of the coating were examined.•In vitro blood compatibility tests revealed neither platelet adhesion nor fibrinogen adsorption.•Surface modification technology of medical devices: non-cytotoxic and no blood clot formation.
