Description
Summary:The formation of films of valve metal oxides of the aluminum, zirconium, titanium, tantalum, niobium series with a thickness of about 100 nm by electrochemical anodization in an electrolyte based on a 1 % aqueous solution of citric acid is considered. The effect of films of anodic oxides of valve metals with a built-in electret charge on the process of blood hemostasis when it contacts the surface of oxide films is studied. It is found that films of oxides with a negative electric charge (oxides of aluminum and zirconium) slow down the process of blood hemostasis, and films of anodic oxides with a positive electric charge (oxides of niobium and tantalum) accelerate it. Recommendations are given for the use of coatings with a negative electric charge as implant coatings to ensure a thromboresistant effect. Positively charged valve metal oxides can be used in wound treatment to stop bleeding.
