Abstract

Abstract:

Ag nanoparticles films were prepared by electrodeposition. The thin films were then treated with a avantin solution of 1H, 1H, 2H, 2H-perfluorooctyl triethoxysilane (25%, volume fraction) for 20 h. After these solution, 316L stainless steel’s surface mircoscopic view changed, so the hydrophobicity and oleophobic property were improved. The blood compatibility effect of the films was tested by dynamic blood coagulation experiment, anticoagulant time measurement, platelet adhesion experiment, hemolysis test, Protein adsorption experiment. As a result, platelet adsorption amount, activity level, albumin absorption amount have improved a lot by the nanometer silver plating on 316L steel surface, other index is similar with the bare steel. Nanometer silver plating on 316L steel surface can improve the blood compatibility of 316L steel. Compared with bare 316L stainless steel, Ag nanoparticles films has a better blood compatibility, it’s a appropriate material for coronary artery stent.

Key words: Facile electrochemical, 316L stainless steel, Ag nanoparticles film, Hydrophobicity, Oleophobic property, Blood compatibility
